+System Control and Power Interface (SCPI) Message Protocol
+----------------------------------------------------------
+
+Firmware implementing the SCPI described in ARM document number ARM DUI 0922B
+("ARM Compute Subsystem SCP: Message Interface Protocols")[0] can be used
+by Linux to initiate various system control and power operations.
+
+Required properties:
+
+- compatible : should be "arm,scpi"
+- mboxes: List of phandle and mailbox channel specifiers
+ All the channels reserved by remote SCP firmware for use by
+ SCPI message protocol should be specified in any order
+- shmem : List of phandle pointing to the shared memory(SHM) area between the
+ processors using these mailboxes for IPC, one for each mailbox
+ SHM can be any memory reserved for the purpose of this communication
+ between the processors.
+
+See Documentation/devicetree/bindings/mailbox/mailbox.txt
+for more details about the generic mailbox controller and
+client driver bindings.
+
+Clock bindings for the clocks based on SCPI Message Protocol
+------------------------------------------------------------
+
+This binding uses the common clock binding[1].
+
+Container Node
+==============
+Required properties:
+- compatible : should be "arm,scpi-clocks"
+ All the clocks provided by SCP firmware via SCPI message
+ protocol much be listed as sub-nodes under this node.
+
+Sub-nodes
+=========
+Required properties:
+- compatible : shall include one of the following
+ "arm,scpi-dvfs-clocks" - all the clocks that are variable and index based.
+ These clocks don't provide an entire range of values between the
+ limits but only discrete points within the range. The firmware
+ provides the mapping for each such operating frequency and the
+ index associated with it. The firmware also manages the
+ voltage scaling appropriately with the clock scaling.
+ "arm,scpi-variable-clocks" - all the clocks that are variable and provide full
+ range within the specified range. The firmware provides the
+ range of values within a specified range.
+
+Other required properties for all clocks(all from common clock binding):
+- #clock-cells : Should be 1. Contains the Clock ID value used by SCPI commands.
+- clock-output-names : shall be the corresponding names of the outputs.
+- clock-indices: The identifying number for the clocks(i.e.clock_id) in the
+ node. It can be non linear and hence provide the mapping of identifiers
+ into the clock-output-names array.
+
+SRAM and Shared Memory for SCPI
+-------------------------------
+
+A small area of SRAM is reserved for SCPI communication between application
+processors and SCP.
+
+Required properties:
+- compatible : should be "arm,juno-sram-ns" for Non-secure SRAM on Juno
+
+The rest of the properties should follow the generic mmio-sram description
+found in ../../misc/sysram.txt
+
+Each sub-node represents the reserved area for SCPI.
+
+Required sub-node properties:
+- reg : The base offset and size of the reserved area with the SRAM
+- compatible : should be "arm,juno-scp-shmem" for Non-secure SRAM based
+ shared memory on Juno platforms
+
+Sensor bindings for the sensors based on SCPI Message Protocol
+--------------------------------------------------------------
+SCPI provides an API to access the various sensors on the SoC.
+
+Required properties:
+- compatible : should be "arm,scpi-sensors".
+- #thermal-sensor-cells: should be set to 1. This property follows the
+ thermal device tree bindings[2].
+
+ Valid cell values are raw identifiers (Sensor
+ ID) as used by the firmware. Refer to
+ platform documentation for your
+ implementation for the IDs to use. For Juno
+ R0 and Juno R1 refer to [3].

+ polling-delay = <1000>;
+
+ /* sensor ID */
+ thermal-sensors = <&scpi_sensors0 3>;
+ ...
+ };
+};
+
+In the above example, the #clock-cells is set to 1 as required.
+scpi_dvfs has 3 output clocks namely: atlclk, aplclk, and gpuclk with 0,
+1 and 2 as clock-indices. scpi_clk has 2 output clocks namely: pxlclk0
+and pxlclk1 with 3 and 4 as clock-indices.
+
+The first consumer in the example is cpu@0 and it has '0' as the clock
+specifier which points to the first entry in the output clocks of
+scpi_dvfs i.e. "atlclk".
+
+Similarly the second example is hdlcd@7ff60000 and it has pxlclk1 as input
+clock. '4' in the clock specifier here points to the second entry
+in the output clocks of scpi_clocks i.e. "pxlclk1"
+
+The thermal-sensors property in the soc_thermal node uses the
+temperature sensor provided by SCP firmware to setup a thermal
+zone. The ID "3" is the sensor identifier for the temperature sensor
+as used by the firmware.

+ARM Juno Boards
+----------------
+The Juno boards are targeting development for AArch64 systems. The first

+with the motherboard part of the hardware being described in a separate file
+to highlight the fact that is part of the support infrastructure for the SoC.
+Juno device tree bindings also share the Versatile Express bindings as
+described under the RS1 memory mapping.

+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:

+ compatible = "brcm,brcmstb-aon-ctrl";
+ reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY). See
+the example device tree snippet below.
+
+== MEMC (MEMory Controller)
+
+Represents a single memory controller instance.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-memc" and "simple-bus"
+
+Should contain subnodes for any of the following relevant hardware resources:
+
+== DDR PHY control
+
+Control registers for this memory controller's DDR PHY.
+
+Required properties:
+- compatible : should contain one of these

+ "brcm,brcmstb-ddr-phy-v240.1"
+ "brcm,brcmstb-ddr-phy-v240.2"
+
+- reg : the DDR PHY register range
+
+== DDR SHIMPHY
+
+Control registers for this memory controller's DDR SHIMPHY.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-ddr-shimphy-v1.0"
+- reg : the DDR SHIMPHY register range
+
+== MEMC DDR control
+
+Sequencer DRAM parameters and control registers. Used for Self-Refresh
+Power-Down (SRPD), among other things.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-memc-ddr"
+- reg : the MEMC DDR register range

+Mediatek vencsys controller
+============================
+
+The Mediatek vencsys controller provides various clocks to the system.
+
+Required Properties:
+
+- compatible: Should be:
+ - "mediatek,mt8173-vencsys", "syscon"
+- #clock-cells: Must be 1
+
+The vencsys controller uses the common clk binding from
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+The available clocks are defined in dt-bindings/clock/mt*-clk.h.
+
+Example:
+
+vencsys: clock-controller@18000000 {
+ compatible = "mediatek,mt8173-vencsys", "syscon";
+ reg = <0 0x18000000 0 0x1000>;

+UniPhier outer cache controller
+
+UniPhier SoCs are integrated with a full-custom outer cache controller system.
+All of them have a level 2 cache controller, and some have a level 3 cache
+controller as well.
+
+Required properties:
+- compatible: should be "socionext,uniphier-system-cache"
+- reg: offsets and lengths of the register sets for the device. It should
+ contain 3 regions: control register, revision register, operation register,
+ in this order.
+- cache-unified: specifies the cache is a unified cache.
+- cache-size: specifies the size in bytes of the cache
+- cache-sets: specifies the number of associativity sets of the cache
+- cache-line-size: specifies the line size in bytes
+- cache-level: specifies the level in the cache hierarchy. The value should
+ be 2 for L2 cache, 3 for L3 cache, etc.
+
+Optional properties:
+- next-level-cache: phandle to the next level cache if present. The next level
+ cache should be also compatible with "socionext,uniphier-system-cache".
+
+The L2 cache must exist to use the L3 cache; the cache hierarchy must be
+indicated correctly with "next-level-cache" properties.

+Child nodes:
+
+An RSB controller node can contain zero or more child nodes representing

+* Marvell PXA1928 Clock Controllers
+
+The PXA1928 clock subsystem generates and supplies clock to various

+blocks called APMU, MPMU, and APBC roughly corresponding to internal buses.
+

+
+- compatible: should be one of the following.
+ - "marvell,pxa1928-apmu" - APMU controller compatible
+ - "marvell,pxa1928-mpmu" - MPMU controller compatible

+- reg: physical base address of the clock controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use the clock controller
+phandle and this identifier to specify the clock which they consume.
+
+All these identifiers can be found in <dt-bindings/clock/marvell,pxa1928.h>.

+- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
+- clock-names: Should contain the following:
+ "cpu" - The multiplexer for clock input of CPU cluster.

+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The DFLL IP block on Tegra is a root clocksource designed for clocking
+the fast CPU cluster. It consists of a free-running voltage controlled
+oscillator connected to the CPU voltage rail (VDD_CPU), and a closed loop
+control module that will automatically adjust the VDD_CPU voltage by
+communicating with an off-chip PMIC either via an I2C bus or via PWM signals.
+Currently only the I2C mode is supported by these bindings.
+
+Required properties:
+- compatible : should be "nvidia,tegra124-dfll"
+- reg : Defines the following set of registers, in the order listed:
+ - registers for the DFLL control logic.
+ - registers for the I2C output logic.

+- interrupts: Should contain the DFLL block interrupt.
+- clocks: Must contain an entry for each entry in clock-names.
+ See clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - soc: Clock source for the DFLL control logic.
+ - ref: The closed loop reference clock
+ - i2c: Clock source for the integrated I2C master.
+- resets: Must contain an entry for each entry in reset-names.

+- reset-names: Must include the following entries:
+ - dvco: Reset control for the DFLL DVCO.
+- #clock-cells: Must be 0.
+- clock-output-names: Name of the clock output.
+- vdd-cpu-supply: Regulator for the CPU voltage rail that the DFLL
+ hardware will start controlling. The regulator will be queried for
+ the I2C register, control values and supported voltages.
+

+- nvidia,sample-rate: Sample rate of the DFLL control loop.
+- nvidia,droop-ctrl: See the register CL_DVFS_DROOP_CTRL in the TRM.
+- nvidia,force-mode: See the field DFLL_PARAMS_FORCE_MODE in the TRM.

+* Rockchip RK3368 Clock and Reset Unit
+
+The RK3368 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3368-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+ If missing, pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3368-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "xin32k" - rtc clock - optional,
+ - "ext_i2s" - external I2S clock - optional,
+ - "ext_gmac" - external GMAC clock - optional
+ - "ext_hsadc" - external HSADC clock - optional,
+ - "ext_isp" - external ISP clock - optional,
+ - "ext_jtag" - external JTAG clock - optional
+ - "ext_vip" - external VIP clock - optional,
+ - "usbotg_out" - output clock of the pll in the otg phy

+STMicroelectronics STM32 Reset and Clock Controller
+===================================================
+
+The RCC IP is both a reset and a clock controller. This documentation only
+describes the clock part.
+
+Please also refer to clock-bindings.txt in this directory for common clock
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,stm32f42xx-rcc"
+- reg: should be register base and length as documented in the
+ datasheet
+- #clock-cells: 2, device nodes should specify the clock in their "clocks"
+ property, containing a phandle to the clock device node, an index selecting
+ between gated clocks and other clocks and an index specifying the clock to
+ use.
+
+Example:
+
+ rcc: rcc@40023800 {
+ #clock-cells = <2>
+ compatible = "st,stm32f42xx-rcc", "st,stm32-rcc";
+ reg = <0x40023800 0x400>;
+ };
+
+Specifying gated clocks
+=======================
+
+The primary index must be set to 0.
+
+The secondary index is the bit number within the RCC register bank, starting
+from the first RCC clock enable register (RCC_AHB1ENR, address offset 0x30).
+
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register (LSB is 0, MSB is 31).
+
+Example:
+
+ /* Gated clock, AHB1 bit 0 (GPIOA) */
+ ... {
+ clocks = <&rcc 0 0>
+ };
+
+ /* Gated clock, AHB2 bit 4 (CRYP) */
+ ... {
+ clocks = <&rcc 0 36>
+ };
+
+Specifying other clocks
+=======================
+
+The primary index must be set to 1.
+
+The secondary index is bound with the following magic numbers:
+
+ 0 SYSTICK
+ 1 FCLK
+
+Example:
+
+ /* Misc clock, FCLK */
+ ... {
+ clocks = <&rcc 1 1>
+ };

+Binding for TO CDCE925 programmable I2C clock synthesizers.
+
+Reference
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] http://www.ti.com/product/cdce925
+
+The driver provides clock sources for each output Y1 through Y5.
+
+Required properties:
+ - compatible: Shall be "ti,cdce925"
+ - reg: I2C device address.
+ - clocks: Points to a fixed parent clock that provides the input frequency.
+ - #clock-cells: From common clock bindings: Shall be 1.
+
+Optional properties:
+ - xtal-load-pf: Crystal load-capacitor value to fine-tune performance on a
+ board, or to compensate for external influences.
+
+For both PLL1 and PLL2 an optional child node can be used to specify spread
+spectrum clocking parameters for a board.
+ - spread-spectrum: SSC mode as defined in the data sheet.
+ - spread-spectrum-center: Use "centered" mode instead of "max" mode. When
+ present, the clock runs at the requested frequency on average. Otherwise
+ the requested frequency is the maximum value of the SCC range.
+
+
+Example:
+
+ clockgen: cdce925pw@64 {
+ compatible = "cdce925";
+ reg = <0x64>;
+ clocks = <&xtal_27Mhz>;
+ #clock-cells = <1>;
+ xtal-load-pf = <5>;
+ /* PLL options to get SSC 1% centered */
+ PLL2 {
+ spread-spectrum = <4>;
+ spread-spectrum-center;
+ };
+ };

+ clock in the prcmu-clock node the consumer wants to use.
+- prcc-periph-clock: a subnode with two clock cells for
+ PRCC (programmable reset- and clock controller) peripheral clocks.
+ The first cell indicates which PRCC block the consumer
+ wants to use, possible values are 1, 2, 3, 5, 6. The second
+ cell indicates which clock inside the PRCC block it wants,
+ possible values are 0 thru 31.
+- prcc-kernel-clock: a subnode with two clock cells for
+ PRCC (programmable reset- and clock controller) kernel clocks
+ The first cell indicates which PRCC block the consumer
+ wants to use, possible values are 1, 2, 3, 5, 6. The second

+Device-Tree bindings for Samsung Exynos SoC mobile image compressor (MIC)
+
+MIC (mobile image compressor) resides between decon and mipi dsi. Mipi dsi is
+not capable to transfer high resoltuion frame data as decon can send. MIC
+solves this problem by compressing the frame data by 1/2 before it is

+the panel PCB.
+
+Required properties:
+- compatible: value should be "samsung,exynos5433-mic".
+- reg: physical base address and length of the MIC registers set and system
+ register of mic.
+- clocks: must include clock specifiers corresponding to entries in the
+ clock-names property.
+- clock-names: list of clock names sorted in the same order as the clocks
+ property. Must contain "pclk_mic0", "sclk_rgb_vclk_to_mic0".

+Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
+
+DECON (Display and Enhancement Controller) is the Display Controller for the
+Exynos series of SoCs which transfers the image data from a video memory
+buffer to an external LCD interface.
+
+Required properties:
+- compatible: value should be "samsung,exynos5433-decon";
+- reg: physical base address and length of the DECON registers set.
+- interrupts: should contain a list of all DECON IP block interrupts in the
+ order: VSYNC, LCD_SYSTEM. The interrupt specifier format
+ depends on the interrupt controller used.
+- interrupt-names: should contain the interrupt names: "vsync", "lcd_sys"
+ in the same order as they were listed in the interrupts
+ property.
+- clocks: must include clock specifiers corresponding to entries in the
+ clock-names property.
+- clock-names: list of clock names sorted in the same order as the clocks
+ property. Must contain "aclk_decon", "aclk_smmu_decon0x",
+ "aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
+ "sclk_decon_eclk"
+- ports: contains a port which is connected to mic node. address-cells and
+ size-cells must 1 and 0, respectively.
+- port: contains an endpoint node which is connected to the endpoint in the mic
+ node. The reg value muset be 0.
+- i80-if-timings: specify whether the panel which is connected to decon uses
+ i80 lcd interface or mipi video interface. This node contains
+ no timing information as that of fimd does. Because there is
+ no register in decon to specify i80 interface timing value,
+ it is not needed, but make it remain to use same kind of node
+ in fimd and exynos7 decon.

+ - solomon,segment-no-remap: Display needs normal (non-inverted) data column
+ to segment mapping
+ - solomon,com-seq: Display uses sequential COM pin configuration
+ - solomon,com-lrremap: Display uses left-right COM pin remap
+ - solomon,com-invdir: Display uses inverted COM pin scan direction
+ - solomon,com-offset: Number of the COM pin wired to the first display line
+ - solomon,prechargep1: Length of deselect period (phase 1) in clock cycles.
+ - solomon,prechargep2: Length of precharge period (phase 2) in clock cycles.
+ This needs to be the higher, the higher the capacitance
+ of the OLED's pixels is

+The eDMA3 consists of two components: Channel controller (CC) and Transfer
+Controller(s) (TC). The CC is the main entry for DMA users since it is
+responsible for the DMA channel handling, while the TCs are responsible to
+execute the actual DMA tansfer.

+- ti,edma-memcpy-channels: List of channels allocated to be used for memcpy, iow
+ these channels will be SW triggered channels. See example.
+- ti,edma-reserved-slot-ranges: PaRAM slot ranges which should not be used by

+Broadcom STB "UPG GIO" GPIO controller
+
+The controller's registers are organized as sets of eight 32-bit
+registers with each set controlling a bank of up to 32 pins. A single
+interrupt is shared for all of the banks handled by the controller.
+
+Required properties:
+
+- compatible:
+ Must be "brcm,brcmstb-gpio"
+
+- reg:
+ Define the base and range of the I/O address space containing
+ the brcmstb GPIO controller registers
+
+- #gpio-cells:
+ Should be <2>. The first cell is the pin number (within the controller's
+ pin space), and the second is used for the following:
+ bit[0]: polarity (0 for active-high, 1 for active-low)
+
+- gpio-controller:
+ Specifies that the node is a GPIO controller.
+
+- brcm,gpio-bank-widths:
+ Number of GPIO lines for each bank. Number of elements must
+ correspond to number of banks suggested by the 'reg' property.
+
+Optional properties:
+
+- interrupts:
+ The interrupt shared by all GPIO lines for this controller.
+
+- interrupt-parent:
+ phandle of the parent interrupt controller
+
+- interrupts-extended:
+ Alternate form of specifying interrupts and parents that allows for
+ multiple parents. This takes precedence over 'interrupts' and
+ 'interrupt-parent'. Wakeup-capable GPIO controllers often route their
+ wakeup interrupt lines through a different interrupt controller than the
+ primary interrupt line, making this property necessary.
+
+- #interrupt-cells:
+ Should be <2>. The first cell is the GPIO number, the second should specify
+ flags. The following subset of flags is supported:
+ - bits[3:0] trigger type and level flags
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ Valid combinations are 1, 2, 3, 4, 8.
+ See also Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

@@ -116,6 +131,30 @@ Every GPIO controller node must contain both an empty "gpio-controller"
property, and a #gpio-cells integer property, which indicates the number of
cells in a gpio-specifier.
+Optionally, a GPIO controller may have a "ngpios" property. This property
+indicates the number of in-use slots of available slots for GPIOs. The
+typical example is something like this: the hardware register is 32 bits
+wide, but only 18 of the bits have a physical counterpart. The driver is
+generally written so that all 32 bits can be used, but the IP block is reused
+in a lot of designs, some using all 32 bits, some using 18 and some using
+12. In this case, setting "ngpios = <18>;" informs the driver that only the
+first 18 GPIOs, at local offset 0 .. 17, are in use.
+
+If these GPIOs do not happen to be the first N GPIOs at offset 0...N-1, an
+additional bitmask is needed to specify which GPIOs are actually in use,
+and which are dummies. The bindings for this case has not yet been
+specified, but should be specified if/when such hardware appears.

+Generic hwlock bindings
+=======================
+
+Generic bindings that are common to all the hwlock platform specific driver
+implementations.
+
+Please also look through the individual platform specific hwlock binding
+documentations for identifying any additional properties specific to that
+platform.
+
+hwlock providers:
+=================
+
+Required properties:
+- #hwlock-cells: Specifies the number of cells needed to represent a
+ specific lock.
+
+hwlock users:
+=============
+
+Consumers that require specific hwlock(s) should specify them using the
+property "hwlocks", and an optional "hwlock-names" property.
+
+Required properties:
+- hwlocks: List of phandle to a hwlock provider node and an
+ associated hwlock args specifier as indicated by
+ #hwlock-cells. The list can have just a single hwlock
+ or multiple hwlocks, with each hwlock represented by
+ a phandle and a corresponding args specifier.
+
+Optional properties:
+- hwlock-names: List of hwlock name strings defined in the same order
+ as the hwlocks, with one name per hwlock. Consumers can
+ use the hwlock-names to match and get a specific hwlock.
+
+
+1. Example of a node using a single specific hwlock:
+
+The following example has a node requesting a hwlock in the bank defined by
+the node hwlock1. hwlock1 is a hwlock provider with an argument specifier
+of length 1.
+
+ node {
+ ...
+ hwlocks = <&hwlock1 2>;
+ ...
+ };
+
+2. Example of a node using multiple specific hwlocks:
+
+The following example has a node requesting two hwlocks, a hwlock within
+the hwlock device node 'hwlock1' with #hwlock-cells value of 1, and another
+hwlock within the hwlock device node 'hwlock2' with #hwlock-cells value of 2.
+
+ node {
+ ...
+ hwlocks = <&hwlock1 2>, <&hwlock2 0 3>;
+ ...
+ };

+Register-based I2C Bus Mux
+
+This binding describes an I2C bus multiplexer that uses a single register
+to route the I2C signals.
+
+Required properties:
+- compatible: i2c-mux-reg
+- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
+ port is connected to.
+* Standard I2C mux properties. See mux.txt in this directory.
+* I2C child bus nodes. See mux.txt in this directory.
+
+Optional properties:
+- reg: this pair of <offset size> specifies the register to control the mux.
+ The <offset size> depends on its parent node. It can be any memory-mapped
+ address. The size must be either 1, 2, or 4 bytes. If reg is omitted, the
+ resource of this device will be used.
+- little-endian: The existence indicates the register is in little endian.
+- big-endian: The existence indicates the register is in big endian.
+ If both little-endian and big-endian are omitted, the endianness of the
+ CPU will be used.
+- write-only: The existence indicates the register is write-only.
+- idle-state: value to set the muxer to when idle. When no value is
+ given, it defaults to the last value used.
+
+Whenever an access is made to a device on a child bus, the value set
+in the revelant node's reg property will be output to the register.
+
+If an idle state is defined, using the idle-state (optional) property,
+whenever an access is not being made to a device on a child bus, the
+register will be set according to the idle value.
+
+If an idle state is not defined, the most recently used value will be
+left programmed into the register.
+
+Example of a mux on PCIe card, the host is a powerpc SoC (big endian):
+
+ i2c-mux {
+ /* the <offset size> depends on the address translation
+ * of the parent device. If omitted, device resource
+ * will be used instead. The size is to determine

+Generic device tree bindings for I2C busses
+===========================================
+
+This document describes generic bindings which can be used to describe I2C
+busses in a device tree.
+
+Required properties
+-------------------
+
+- #address-cells - should be <1>. Read more about addresses below.
+- #size-cells - should be <0>.
+- compatible - name of I2C bus controller following generic names
+ recommended practice.
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+
+The cells properties above define that an address of children of an I2C bus
+are described by a single value. This is usually a 7 bit address. However,
+flags can be attached to the address. I2C_TEN_BIT_ADDRESS is used to mark a 10
+bit address. It is needed to avoid the ambiguity between e.g. a 7 bit address
+of 0x50 and a 10 bit address of 0x050 which, in theory, can be on the same bus.
+Another flag is I2C_OWN_SLAVE_ADDRESS to mark addresses on which we listen to
+be devices ourselves.
+
+Optional properties
+-------------------
+
+These properties may not be supported by all drivers. However, if a driver
+wants to support one of the below features, it should adapt the bindings below.
+
+- clock-frequency - frequency of bus clock in Hz.
+- wakeup-source - device can be used as a wakeup source.
+
+- interrupts - interrupts used by the device.
+- interrupt-names - "irq" and "wakeup" names are recognized by I2C core,
+ other names are left to individual drivers.
+
+Binding may contain optional "interrupts" property, describing interrupts
+used by the device. I2C core will assign "irq" interrupt (or the very first
+interrupt if not using interrupt names) as primary interrupt for the slave.
+
+Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
+interrupt for the device. If "wakeup" interrupt name is not present in the
+binding, then primary interrupt will be used as wakeup interrupt.

+This document describes the generic device tree binding for MSI controllers and
+their master(s).
+
+Message Signaled Interrupts (MSIs) are a class of interrupts generated by a
+write to an MMIO address.
+
+MSIs were originally specified by PCI (and are used with PCIe), but may also be
+used with other busses, and hence a mechanism is required to relate devices on
+those busses to the MSI controllers which they are capable of using,
+potentially including additional information.
+
+MSIs are distinguished by some combination of:
+
+- The doorbell (the MMIO address written to).
+
+ Devices may be configured by software to write to arbitrary doorbells which
+ they can address. An MSI controller may feature a number of doorbells.
+
+- The payload (the value written to the doorbell).
+
+ Devices may be configured to write an arbitrary payload chosen by software.
+ MSI controllers may have restrictions on permitted payloads.
+
+- Sideband information accompanying the write.
+
+ Typically this is neither configurable nor probeable, and depends on the path
+ taken through the memory system (i.e. it is a property of the combination of
+ MSI controller and device rather than a property of either in isolation).
+
+
+MSI controllers:
+================
+
+An MSI controller signals interrupts to a CPU when a write is made to an MMIO
+address by some master. An MSI controller may feature a number of doorbells.
+
+Required properties:
+--------------------
+
+- msi-controller: Identifies the node as an MSI controller.
+
+Optional properties:
+--------------------
+
+- #msi-cells: The number of cells in an msi-specifier, required if not zero.
+
+ Typically this will encode information related to sideband data, and will
+ not encode doorbells or payloads as these can be configured dynamically.
+
+ The meaning of the msi-specifier is defined by the device tree binding of
+ the specific MSI controller.
+
+
+MSI clients
+===========
+
+MSI clients are devices which generate MSIs. For each MSI they wish to
+generate, the doorbell and payload may be configured, though sideband
+information may not be configurable.
+
+Required properties:
+--------------------
+
+- msi-parent: A list of phandle + msi-specifier pairs, one for each MSI
+ controller which the device is capable of using.
+
+ This property is unordered, and MSIs may be allocated from any combination of
+ MSI controllers listed in the msi-parent property.
+
+ If a device has restrictions on the allocation of MSIs, these restrictions
+ must be described with additional properties.
+
+ When #msi-cells is non-zero, busses with an msi-parent will require
+ additional properties to describe the relationship between devices on the bus
+ and the set of MSIs they can potentially generate.
+
+
+Example
+=======
+
+/ {
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ msi_a: msi-controller@a {
+ reg = <0xa 0xf00>;
+ compatible = "vendor-a,some-controller";
+ msi-controller;
+ /* No sideband data, so #msi-cells omitted */
+ };
+
+ msi_b: msi-controller@b {
+ reg = <0xb 0xf00>;
+ compatible = "vendor-b,another-controller";
+ msi-controller;
+ /* Each device has some unique ID */
+ #msi-cells = <1>;
+ };
+
+ msi_c: msi-controller@c {
+ reg = <0xb 0xf00>;

+* ARM SMMUv3 Architecture Implementation
+
+The SMMUv3 architecture is a significant deparature from previous
+revisions, replacing the MMIO register interface with in-memory command
+and event queues and adding support for the ATS and PRI components of
+the PCIe specification.
+
+** SMMUv3 required properties:
+
+- compatible : Should include:
+
+ * "arm,smmu-v3" for any SMMUv3 compliant
+ implementation. This entry should be last in the
+ compatible list.
+
+- reg : Base address and size of the SMMU.
+
+- interrupts : Non-secure interrupt list describing the wired
+ interrupt sources corresponding to entries in
+ interrupt-names. If no wired interrupts are
+ present then this property may be omitted.
+
+- interrupt-names : When the interrupts property is present, should
+ include the following:
+ * "eventq" - Event Queue not empty
+ * "priq" - PRI Queue not empty
+ * "cmdq-sync" - CMD_SYNC complete
+ * "gerror" - Global Error activated
+
+** SMMUv3 optional properties:
+
+- dma-coherent : Present if DMA operations made by the SMMU (page
+ table walks, stream table accesses etc) are cache
+ coherent with the CPU.
+
+ NOTE: this only applies to the SMMU itself, not
+ masters connected upstream of the SMMU.
+
+- msi-parent : See the generic MSI binding described in
+ devicetree/bindings/interrupt-controller/msi.txt
+ for a description of the msi-parent property.
+
+- hisilicon,broken-prefetch-cmd
+ : Avoid sending CMD_PREFETCH_* commands to the SMMU.
+
+** Example

+LEDs connected to Broadcom BCM6328 controller
+
+This controller is present on BCM6318, BCM6328, BCM6362 and BCM63268.
+In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
+However, on some devices there are Serial LEDs (LEDs connected to a 74x164
+controller), which can either be controlled by software (exporting the 74x164
+as spi-gpio. See Documentation/devicetree/bindings/gpio/gpio-74x164.txt), or
+by hardware using this driver.
+Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
+exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
+controlled, so the only chance to keep them working is by using this driver.
+
+BCM6328 LED controller has a HWDIS register, which controls whether a LED
+should be controlled by a hardware signal instead of the MODE register value,
+with 0 meaning hardware control enabled and 1 hardware control disabled. This
+is usually 1:1 for hardware to LED signals, but through the activity/link
+registers you have some limited control over rerouting the LEDs (as
+explained later in brcm,link-signal-sources). Even if a LED is hardware
+controlled you are still able to make it blink or light it up if it isn't,
+but you can't turn it off if the hardware decides to light it up. For this
+reason, hardware controlled LEDs aren't registered as LED class devices.
+
+Required properties:
+ - compatible : should be "brcm,bcm6328-leds".
+ - #address-cells : must be 1.
+ - #size-cells : must be 0.
+ - reg : BCM6328 LED controller address and size.
+
+Optional properties:
+ - brcm,serial-leds : Boolean, enables Serial LEDs.
+ Default : false
+ - brcm,serial-mux : Boolean, enables Serial LEDs multiplexing.
+ Default : false
+ - brcm,serial-clk-low : Boolean, makes clock signal active low.

+ Default : false

+Each LED is represented as a sub-node of the brcm,bcm6328-leds device.
+
+LED sub-node required properties:
+ - reg : LED pin number (only LEDs 0 to 23 are valid).
+

+ Default : false
+ - brcm,link-signal-sources : An array of hardware link

+LEDs connected to Broadcom BCM6358 controller
+
+This controller is present on BCM6358 and BCM6368.
+In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
+which can either be controlled by software (exporting the 74x164 as spi-gpio.
+See Documentation/devicetree/bindings/gpio/gpio-74x164.txt), or
+by hardware using this driver.
+
+Required properties:
+ - compatible : should be "brcm,bcm6358-leds".
+ - #address-cells : must be 1.
+ - #size-cells : must be 0.
+ - reg : BCM6358 LED controller address and size.

+ Default : 1
+ - brcm,clk-dat-low : Boolean, makes clock and data signals active low.
+ Default : false
+
+Each LED is represented as a sub-node of the brcm,bcm6358-leds device.

+* Kinetic Technologies - KTD2692 Flash LED Driver
+
+KTD2692 is the ideal power solution for high-power flash LEDs.
+It uses ExpressWire single-wire programming for maximum flexibility.
+
+The ExpressWire interface through CTRL pin can control LED on/off and
+enable/disable the IC, Movie(max 1/3 of Flash current) / Flash mode current,
+Flash timeout, LVP(low voltage protection).
+
+Also, When the AUX pin is pulled high while CTRL pin is high,
+LED current will be ramped up to the flash-mode current level.
+
+Required properties:
+- compatible : Should be "kinetic,ktd2692".
+- ctrl-gpios : Specifier of the GPIO connected to CTRL pin.
+- aux-gpios : Specifier of the GPIO connected to AUX pin.
+
+Optional properties:
+- vin-supply : "vin" LED supply (2.7V to 5.5V).
+ See Documentation/devicetree/bindings/regulator/regulator.txt
+
+A discrete LED element connected to the device must be represented by a child
+node - See Documentation/devicetree/bindings/leds/common.txt
+
+Required properties for flash LED child nodes:
+ See Documentation/devicetree/bindings/leds/common.txt
+- led-max-microamp : Minimum Threshold for Timer protection
+ is defined internally (Maximum 300mA).
+- flash-max-microamp : Flash LED maximum current
+ Formula : I(mA) = 15000 / Rset.
+- flash-max-timeout-us : Flash LED maximum timeout.

+STMicroelectronics STi c8sectpfe binding
+============================================
+
+This document describes the c8sectpfe device bindings that is used to get transport
+stream data into the SoC on the TS pins, and into DDR for further processing.
+
+It is typically used in conjunction with one or more demodulator and tuner devices
+which converts from the RF to digital domain. Demodulators and tuners are usually
+located on an external DVB frontend card connected to SoC TS input pins.
+
+Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
+
+Required properties (controller (parent) node):
+- compatible : Should be "stih407-c8sectpfe"
+
+- reg : Address and length of register sets for each device in
+ "reg-names"
+
+- reg-names : The names of the register addresses corresponding to the
+ registers filled in "reg":
+ - c8sectpfe: c8sectpfe registers
+ - c8sectpfe-ram: c8sectpfe internal sram
+
+- clocks : phandle list of c8sectpfe clocks
+- clock-names : should be "c8sectpfe"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- pinctrl-names : a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
+ must be defined for each tsin child node.
+- pinctrl-0 : phandle referencing pin configuration for this tsin configuration
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+
+Required properties (tsin (child) node):
+
+- tsin-num : tsin id of the InputBlock (must be between 0 to 6)
+- i2c-bus : phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
+- rst-gpio : reset gpio for this tsin channel.
+
+Optional properties (tsin (child) node):
+
+- invert-ts-clk : Bool property to control sense of ts input clock (data stored on falling edge of clk).
+- serial-not-parallel : Bool property to configure input bus width (serial on ts_data<7>).
+- async-not-sync : Bool property to control if data is received in asynchronous mode
+ (all bits/bytes with ts_valid or ts_packet asserted are valid).
+
+- dvb-card : Describes the NIM card connected to this tsin channel.
+

+up application processors and peripherals, a 2-channel 32kHz clock outputs,
+a Real-Time-Clock (RTC) and a I2C interface to program the individual
+regulators, clocks outputs and the RTC.
+
+Bindings for the built-in 32k clock generator block and
+regulators are defined in ../clk/maxim,max77802.txt and
+../regulator/max77802.txt respectively.
+
+Required properties:

+Imagination University Program MIPSfpga
+=======================================
+
+Under the Imagination University Program, a microAptiv UP core has been
+released for academic usage.
+
+As we are dealing with a MIPS core instantiated on an FPGA, specifications
+are fluid and can be varied in RTL.
+
+This binding document is provided as baseline guidance for the example
+project provided by IMG.
+
+The example project runs on the Nexys4DDR board by Digilent powered by
+the ARTIX-7 FPGA by Xilinx.
+
+Relevant details about the example project and the Nexys4DDR board:
+
+- microAptiv UP core m14Kc
+- 50MHz clock speed
+- 128Mbyte DDR RAM at 0x0000_0000
+- 8Kbyte RAM at 0x1000_0000
+- axi_intc at 0x1020_0000
+- axi_uart16550 at 0x1040_0000
+- axi_gpio at 0x1060_0000
+- axi_i2c at 0x10A0_0000
+- custom_gpio at 0x10C0_0000
+- axi_ethernetlite at 0x10E0_0000
+- 8Kbyte BootRAM at 0x1FC0_0000
+
+Required properties:
+--------------------
+ - compatible: Must include "digilent,nexys4ddr","img,xilfpga".
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Required properties:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mips,m14Kc".
+ - reg: Must be <0>.
+ - clocks: phandle to ext clock for fixed-clock received by MIPS core.
+
+Example:
+
+ compatible = "img,xilfpga","digilent,nexys4ddr";
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "mips,m14Kc";
+ reg = <0>;
+ clocks = <&ext>;
+ };
+ };
+
+ ext: ext {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <50000000>;
+ };
+
+Boot protocol:
+--------------
+
+The BootRAM is a writeable "RAM" in FPGA at 0x1FC0_0000.
+This is for easy reprogrammibility via JTAG.
+
+The BootRAM initializes the cache and the axi_uart peripheral.
+
+DDR initialization is already handled by a HW IP block.
+
+When the example project bitstream is loaded, the cpu_reset button
+needs to be pressed.
+
+The bootram initializes the cache and axi_uart.
+Then outputs MIPSFPGA\n\r on the serial port on the Nexys4DDR board.
+
+At this point, the board is ready to load the Linux kernel
+vmlinux file via JTAG.

+* Broadcom STB NAND Controller
+
+The Broadcom Set-Top Box NAND controller supports low-level access to raw NAND
+flash chips. It has a memory-mapped register interface for both control
+registers and for its data input/output buffer. On some SoCs, this controller is
+paired with a custom DMA engine (inventively named "Flash DMA") which supports
+basic PROGRAM and READ functions, among other features.
+
+This controller was originally designed for STB SoCs (BCM7xxx) but is now
+available on a variety of Broadcom SoCs, including some BCM3xxx, BCM63xx, and
+iProc/Cygnus. Its history includes several similar (but not fully register
+compatible) versions.
+
+Required properties:
+- compatible : May contain an SoC-specific compatibility string (see below)
+ to account for any SoC-specific hardware bits that may be
+ added on top of the base core controller.
+ In addition, must contain compatibility information about
+ the core NAND controller, of the following form:
+ "brcm,brcmnand" and an appropriate version compatibility
+ string, like "brcm,brcmnand-v7.0"
+ Possible values:
+ brcm,brcmnand-v4.0
+ brcm,brcmnand-v5.0
+ brcm,brcmnand-v6.0
+ brcm,brcmnand-v6.1
+ brcm,brcmnand-v7.0
+ brcm,brcmnand-v7.1
+ brcm,brcmnand
+- reg : the register start and length for NAND register region.
+ (optional) Flash DMA register range (if present)
+ (optional) NAND flash cache range (if at non-standard offset)
+- reg-names : a list of the names corresponding to the previous register
+ ranges. Should contain "nand" and (optionally)
+ "flash-dma" and/or "nand-cache".
+- interrupts : The NAND CTLRDY interrupt and (if Flash DMA is available)
+ FLASH_DMA_DONE
+- interrupt-names : May be "nand_ctlrdy" or "flash_dma_done", if broken out as
+ individual interrupts.
+ May be "nand", if the SoC has the individual NAND
+ interrupts multiplexed behind another custom piece of
+ hardware
+- interrupt-parent : See standard interrupt bindings
+- #address-cells : <1> - subnodes give the chip-select number
+- #size-cells : <0>
+
+Optional properties:

+ (WP) control bit. It is always available on >=
+ v7.0. Use this property to describe the rare
+ earlier versions of this core that include WP
+
+ -- Additonal SoC-specific NAND controller properties --
+
+The NAND controller is integrated differently on the variety of SoCs on which it
+is found. Part of this integration involves providing status and enable bits
+with which to control the 8 exposed NAND interrupts, as well as hardware for
+configuring the endianness of the data bus. On some SoCs, these features are
+handled via standard, modular components (e.g., their interrupts look like a
+normal IRQ chip), but on others, they are controlled in unique and interesting
+ways, sometimes with registers that lump multiple NAND-related functions
+together. The former case can be described simply by the standard interrupts
+properties in the main controller node. But for the latter exceptional cases,
+we define additional 'compatible' properties and associated register resources within the NAND controller node above.
+
+ - compatible: Can be one of several SoC-specific strings. Each SoC may have
+ different requirements for its additional properties, as described below each
+ bullet point below.
+
+ * "brcm,nand-bcm63138"
+ - reg: (required) the 'NAND_INT_BASE' register range, with separate status
+ and enable registers
+ - reg-names: (required) "nand-int-base"
+
+ * "brcm,nand-iproc"
+ - reg: (required) the "IDM" register range, for interrupt enable and APB
+ bus access endianness configuration, and the "EXT" register range,
+ for interrupt status/ack.
+ - reg-names: (required) a list of the names corresponding to the previous
+ register ranges. Should contain "iproc-idm" and "iproc-ext".
+
+
+* NAND chip-select
+
+Each controller (compatible: "brcm,brcmnand") may contain one or more subnodes
+to represent enabled chip-selects which (may) contain NAND flash chips. Their
+properties are as follows.
+
+Required properties:
+- compatible : should contain "brcm,nandcs"
+- reg : a single integer representing the chip-select
+ number (e.g., 0, 1, 2, etc.)
+- #address-cells : see partition.txt
+- #size-cells : see partition.txt
+- nand-ecc-strength : see nand.txt
+- nand-ecc-step-size : must be 512 or 1024. See nand.txt
+
+Optional properties:
+- nand-on-flash-bbt : boolean, to enable the on-flash BBT for this
+ chip-select. See nand.txt
+- brcm,nand-oob-sector-size : integer, to denote the spare area sector size
+ expected for the ECC layout in use. This size, in
+ addition to the strength and step-size,
+ determines how the hardware BCH engine will lay
+ out the parity bytes it stores on the flash.
+ This property can be automatically determined by
+ the flash geometry (particularly the NAND page
+ and OOB size) in many cases, but when booting
+ from NAND, the boot controller has only a limited
+ number of available options for its default ECC
+ layout.
+
+Each nandcs device node may optionally contain sub-nodes describing the flash
+partition mapping. See partition.txt for more detail.
+
+
+Example:
+
+nand@f0442800 {
+ compatible = "brcm,brcmnand-v7.0", "brcm,brcmnand";

+Freescale's NAND flash controller (NFC)
+
+This variant of the Freescale NAND flash controller (NFC) can be found on
+Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc".
+- reg: address range of the NFC.
+- interrupts: interrupt of the NFC.
+- #address-cells: shall be set to 1. Encode the nand CS.
+- #size-cells : shall be set to 0.
+- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
+- assigned-clock-rates: The NAND bus timing is derived from this clock
+ rate and should not exceed maximum timing for any NAND memory chip
+ in a board stuffing. Typical NAND memory timings derived from this
+ clock are found in the SoC hardware reference manual. Furthermore,
+ there might be restrictions on maximum rates when using hardware ECC.
+
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+ representing partitions.
+
+Required children nodes:
+Children nodes represent the available nand chips. Currently the driver can
+only handle one NAND chip.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc-cs".
+- nand-bus-width: see nand.txt
+- nand-ecc-mode: see nand.txt
+
+Required properties for hardware ECC:
+- nand-ecc-strength: supported strengths are 24 and 32 bit (see nand.txt)
+- nand-ecc-step-size: step size equals page size, currently only 2k pages are
+ supported
+- nand-on-flash-bbt: see nand.txt

+Generic OPP (Operating Performance Points) Bindings
+----------------------------------------------------
+
+Devices work at voltage-current-frequency combinations and some implementations
+have the liberty of choosing these. These combinations are called Operating
+Performance Points aka OPPs. This document defines bindings for these OPPs
+applicable across wide range of devices. For illustration purpose, this document
+uses CPU as a device.
+
+This document contain multiple versions of OPP binding and only one of them
+should be used per device.
+
+Binding 1: operating-points
+============================
+
+This binding only supports voltage-frequency pairs.
+
+Properties:
+- operating-points: An array of 2-tuples items, and each item consists
+ of frequency and voltage like <freq-kHz vol-uV>.
+ freq: clock frequency in kHz
+ vol: voltage in microvolt
+
+Examples:
+
+cpu@0 {
+ compatible = "arm,cortex-a9";
+ reg = <0>;
+ next-level-cache = <&L2>;
+ operating-points = <
+ /* kHz uV */
+ 792000 1100000
+ 396000 950000
+ 198000 850000
+ >;
+};
+
+
+Binding 2: operating-points-v2
+============================
+
+* Property: operating-points-v2
+
+Devices supporting OPPs must set their "operating-points-v2" property with
+phandle to a OPP table in their DT node. The OPP core will use this phandle to
+find the operating points for the device.
+
+Devices may want to choose OPP tables at runtime and so can provide a list of
+phandles here. But only *one* of them should be chosen at runtime. This must be
+accompanied by a corresponding "operating-points-names" property, to uniquely
+identify the OPP tables.
+
+If required, this can be extended for SoC vendor specfic bindings. Such bindings
+should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
+and should have a compatible description like: "operating-points-v2-<vendor>".
+
+Optional properties:
+- operating-points-names: Names of OPP tables (required if multiple OPP
+ tables are present), to uniquely identify them. The same list must be present
+ for all the CPUs which are sharing clock/voltage rails and hence the OPP
+ tables.
+
+* OPP Table Node
+
+This describes the OPPs belonging to a device. This node can have following
+properties:
+
+Required properties:
+- compatible: Allow OPPs to express their compatibility. It should be:
+ "operating-points-v2".
+
+- OPP nodes: One or more OPP nodes describing voltage-current-frequency
+ combinations. Their name isn't significant but their phandle can be used to
+ reference an OPP.
+
+Optional properties:
+- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
+ switch their DVFS state together, i.e. they share clock/voltage/current lines.
+ Missing property means devices have independent clock/voltage/current lines,
+ but they share OPP tables.
+
+- status: Marks the OPP table enabled/disabled.
+
+
+* OPP Node
+
+This defines voltage-current-frequency combinations along with other related
+properties.
+
+Required properties:
+- opp-hz: Frequency in Hz, expressed as a 64-bit big-endian integer.
+
+Optional properties:
+- opp-microvolt: voltage in micro Volts.
+
+ A single regulator's voltage is specified with an array of size one or three.
+ Single entry is for target voltage and three entries are for <target min max>
+ voltages.
+
+ Entries for multiple regulators must be present in the same order as
+ regulators are specified in device's DT node.
+
+- opp-microamp: The maximum current drawn by the device in microamperes
+ considering system specific parameters (such as transients, process, aging,
+ maximum operating temperature range etc.) as necessary. This may be used to
+ set the most efficient regulator operating mode.
+
+ Should only be set if opp-microvolt is set for the OPP.
+
+ Entries for multiple regulators must be present in the same order as
+ regulators are specified in device's DT node. If this property isn't required
+ for few regulators, then this should be marked as zero for them. If it isn't
+ required for any regulator, then this property need not be present.
+
+- clock-latency-ns: Specifies the maximum possible transition latency (in
+ nanoseconds) for switching to this OPP from any other OPP.
+
+- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
+ available on some platforms, where the device can run over its operating
+ frequency for a short duration of time limited by the device's power, current
+ and thermal limits.
+
+- opp-suspend: Marks the OPP to be used during device suspend. Only one OPP in
+ the table should have this.
+
+- status: Marks the node enabled/disabled.
+
+Example 1: Single cluster Dual-core ARM cortex A9, switch DVFS states together.

+This document describes the generic device tree binding for describing the
+relationship between PCI devices and MSI controllers.
+
+Each PCI device under a root complex is uniquely identified by its Requester ID
+(AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
+Function number.
+
+For the purpose of this document, when treated as a numeric value, a RID is
+formatted such that:
+
+* Bits [15:8] are the Bus number.
+* Bits [7:3] are the Device number.
+* Bits [2:0] are the Function number.
+* Any other bits required for padding must be zero.
+
+MSIs may be distinguished in part through the use of sideband data accompanying
+writes. In the case of PCI devices, this sideband data may be derived from the
+Requester ID. A mechanism is required to associate a device with both the MSI
+controllers it can address, and the sideband data that will be associated with
+its writes to those controllers.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.

+ (rid-base,msi-controller,msi-base,length), where:
+
+ * rid-base is a single cell describing the first RID matched by the entry.
+
+ * msi-controller is a single phandle to an MSI controller
+
+ * msi-base is an msi-specifier describing the msi-specifier produced for the
+ first RID matched by the entry.
+
+ * length is a single cell describing how many consecutive RIDs are matched
+ following the rid-base.
+
+ Any RID r in the interval [rid-base, rid-base + length) is associated with
+ the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
+
+- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
+ to an msi-specifier per the msi-map property.
+
+- msi-parent: Describes the MSI parent of the root complex itself. Where
+ the root complex and MSI controller do not pass sideband data with MSI
+ writes, this property may be used to describe the MSI controller(s)
+ used by PCI devices under the root complex, if defined as such in the
+ binding for the root complex.

+
+Required nodes : a sub-node is required for each port the controller
+ provides. Address range information including the usual
+ 'reg' property is used inside these nodes to describe
+ the controller's topology.
+
+Required properties (port (child) node):
+- reg : address and length of the register set for the port.
+- #phy-cells : should be 1 (See second example)

+* Pin-controller driver for the Marvell Berlin SoCs

+Pin control registers are part of both chip controller and system
+controller register sets. Pin controller nodes should be a sub-node of
+either the chip controller or system controller node. The pins
+controlled are organized in groups, so no actual pin information is

+A pin-controller node should contain subnodes representing the pin group
+configurations, one per function. Each subnode has the group name and

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+ size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+ second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+ for possible values.
+
+For example, the following is the bare minimum node:
+
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+ configured by this node. The format of a pin name string is "GP_xy", where x
+ is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+ "gpio", "client_a", "client_b", "client_c"
+
+Example:
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+
+ uart0_default: uart0_active {
+ data_signals {
+ pins = "GP_O0", "GP_O1";
+ function = "client_b";
+ };
+ };
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ ...
+ pinctrl-0 = <&uart0_default>;
+ pinctrl-names = "default";
+ };
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

+* Freescale i.MX7 Dual IOMUX Controller
+
+iMX7D supports two iomuxc controllers, fsl,imx7d-iomuxc controller is similar
+as previous iMX SoC generation and fsl,imx7d-iomuxc-lpsr which provides low
+power state retention capabilities on gpios that are part of iomuxc-lpsr
+(GPIO1_IO7..GPIO1_IO0). While iomuxc-lpsr provides its own set of registers for
+mux and pad control settings, it shares the input select register from main
+iomuxc controller for daisy chain settings, the fsl,input-sel property extends
+fsl,imx-pinctrl driver to support iomuxc-lpsr controller.
+
+iomuxc_lpsr: iomuxc-lpsr@302c0000 {
+ compatible = "fsl,imx7d-iomuxc-lpsr";
+ reg = <0x302c0000 0x10000>;
+ fsl,input-sel = <&iomuxc>;
+};
+
+iomuxc: iomuxc@30330000 {
+ compatible = "fsl,imx7d-iomuxc";
+ reg = <0x30330000 0x10000>;
+};
+
+Pheriparials using pads from iomuxc-lpsr support low state retention power
+state, under LPSR mode GPIO's state of pads are retain.
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx7d-iomuxc" for main IOMUXC controller, or
+ "fsl,imx7d-iomuxc-lpsr" for Low Power State Retention IOMUXC controller.
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx7d-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. Please refer to i.MX7 Dual
+ Reference Manual for detailed CONFIG settings.
+- fsl,input-sel: required property for iomuxc-lpsr controller, this property is
+ a phandle for main iomuxc controller which shares the input select register for
+ daisy chain settings.
+
+CONFIG bits definition:
+PAD_CTL_PUS_100K_DOWN (0 << 5)
+PAD_CTL_PUS_5K_UP (1 << 5)
+PAD_CTL_PUS_47K_UP (2 << 5)
+PAD_CTL_PUS_100K_UP (3 << 5)
+PAD_CTL_PUE (1 << 4)
+PAD_CTL_HYS (1 << 3)
+PAD_CTL_SRE_SLOW (1 << 2)
+PAD_CTL_SRE_FAST (0 << 2)
+PAD_CTL_DSE_X1 (0 << 0)
+PAD_CTL_DSE_X2 (1 << 0)
+PAD_CTL_DSE_X3 (2 << 0)
+PAD_CTL_DSE_X4 (3 << 0)
+
+Examples:
+While iomuxc-lpsr is intended to be used by dedicated peripherals to take
+advantages of LPSR power mode, is also possible that an IP to use pads from
+any of the iomux controllers. For example the I2C1 IP can use SCL pad from
+iomuxc-lpsr controller and SDA pad from iomuxc controller as:
+
+i2c1: i2c@30a20000 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_i2c1_1 &pinctrl_i2c1_2>;
+ status = "okay";
+};
+
+iomuxc-lpsr@302c0000 {
+ compatible = "fsl,imx7d-iomuxc-lpsr";
+ reg = <0x302c0000 0x10000>;
+ fsl,input-sel = <&iomuxc>;
+
+ pinctrl_i2c1_1: i2c1grp-1 {
+ fsl,pins = <
+ MX7D_PAD_GPIO1_IO04__I2C1_SCL 0x4000007f

+Imagination Technologies Pistachio SoC pin controllers
+======================================================
+
+The pin controllers on Pistachio are a combined GPIO controller, (GPIO)
+interrupt controller, and pinmux + pinconf device. The system ("east") pin
+controller on Pistachio has 99 pins, 90 of which are MFIOs which can be
+configured as GPIOs. The 90 GPIOs are divided into 6 banks of up to 16 GPIOs
+each. The GPIO banks are represented as sub-nodes of the pad controller node.
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+Required properties for pin controller node:
+--------------------------------------------
+ - compatible: "img,pistachio-system-pinctrl".
+ - reg: Address range of the pinctrl registers.
+
+Required properties for GPIO bank sub-nodes:
+--------------------------------------------
+ - interrupts: Interrupt line for the GPIO bank.
+ - gpio-controller: Indicates the device is a GPIO controller.
+ - #gpio-cells: Must be two. The first cell is the GPIO pin number and the
+ second cell indicates the polarity. See <dt-bindings/gpio/gpio.h> for
+ a list of possible values.
+ - interrupt-controller: Indicates the device is an interrupt controller.
+ - #interrupt-cells: Must be two. The first cell is the GPIO pin number and
+ the second cell encodes the interrupt flags. See
+ <dt-bindings/interrupt-controller/irq.h> for a list of valid flags.
+
+Note that the N GPIO bank sub-nodes *must* be named gpio0, gpio1, ... gpioN-1.
+
+Required properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - pins: List of pins to which the configuration applies. See below for a
+ list of possible pins.
+
+Optional properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - function: Mux function for the specified pins. This is not applicable for
+ non-MFIO pins. See below for a list of valid functions for each pin.
+ - bias-high-impedance: Enable high-impedance mode.
+ - bias-pull-up: Enable weak pull-up.
+ - bias-pull-down: Enable weak pull-down.
+ - bias-bus-hold: Enable bus-keeper mode.
+ - drive-strength: Drive strength in mA. Supported values: 2, 4, 8, 12.
+ - input-schmitt-enable: Enable Schmitt trigger.
+ - input-schmitt-disable: Disable Schmitt trigger.
+ - slew-rate: Slew rate control. 0 for slow, 1 for fast.

+- reg : Address and length of the register set for the device
+- clocks : Clock specifier (see clock bindings for details)
+
+The lpc1850-scu driver uses the generic pin multiplexing and generic pin
+configuration documented in pinctrl-bindings.txt.
+
+The following generic nodes are supported:
+ - function
+ - pins
+ - bias-disable
+ - bias-pull-up
+ - bias-pull-down
+ - drive-strength
+ - input-enable
+ - input-disable
+ - input-schmitt-enable
+ - input-schmitt-disable
+ - slew-rate
+
+Not all pins support all properties so either refer to the NXP 1850/4350
+user manual or the pin table in the pinctrl-lpc18xx driver for supported
+pin properties.
+
+Example:
+pinctrl: pinctrl@40086000 {

+SiRFatlas7's pinmux nodes act as a container for an abitrary number of subnodes.
+Each of these subnodes represents some desired configuration for a group of pins.
+
+Required subnode-properties:
+- groups : An array of strings. Each string contains the name of a group.
+- function: A string containing the name of the function to mux to the
+ group.
+
+ Valid values for group and function names can be found from looking at the
+ group and function arrays in driver files:
+ drivers/pinctrl/pinctrl-sirf.c
+

+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for pins are:
+ gpio0-gpio172, sdc3_clk, sdc3_cmd, sdc3_data sdc4_clk, sdc4_cmd, sdc4_data
+
+Valid values for function are:
+ gpio, cam_mclk, dsub, ext_gps, gp_clk_0a, gp_clk_0b, gp_clk_1a, gp_clk_1b,

+Specifying wakeup capability for devices
+============================================
+
+Any device nodes
+----------------
+Nodes that describe devices which has wakeup capability must contain an
+"wakeup-source" boolean property.
+
+Also, if device is marked as a wakeup source, then all the primary
+interrupt(s) can be used as wakeup interrupt(s).
+
+However if the devices have dedicated interrupt as the wakeup source
+then they need to specify/identify the same using device specific
+interrupt name. In such cases only that interrupt can be used as wakeup
+interrupt.

+Binding for Maxim MAX77686 regulators
+
+This is a part of the device tree bindings of MAX77686 multi-function device.
+More information can be found in ../mfd/max77686.txt file.
+
+The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- voltage-regulators : The regulators of max77686 have to be instantiated
+ under subnode named "voltage-regulators" using the following format.
+
+ regulator_name {
+ regulator-compatible = LDOn/BUCKn
+ standard regulator constraints....
+ };
+ refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+ The regulator node's name should be initialized with a string
+to get matched with their hardware counterparts as follow:
+
+ -LDOn : for LDOs, where n can lie in range 1 to 26.
+ example: LDO1, LDO2, LDO26.
+ -BUCKn : for BUCKs, where n can lie in range 1 to 9.
+ example: BUCK1, BUCK5, BUCK9.
+
+ Regulators which can be turned off during system suspend:
+ -LDOn : 2, 6-8, 10-12, 14-16,
+ -BUCKn : 1-4.
+ Use standard regulator bindings for it ('regulator-off-in-suspend').
+
+ LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
+ control. To turn this feature on this property must be added to the regulator
+ sub-node:
+ - maxim,ena-gpios : one GPIO specifier enable control (the gpio
+ flags are actually ignored and always
+ ACTIVE_HIGH is used)
+

+Bindings for the Generic PWM Regulator
+======================================
+
+Currently supports 2 modes of operation:
+
+Voltage Table: When in this mode, a voltage table (See below) of
+ predefined voltage <=> duty-cycle values must be
+ provided via DT. Limitations are that the regulator can
+ only operate at the voltages supplied in the table.
+ Intermediary duty-cycle values which would normally
+ allow finer grained voltage selection are ignored and
+ rendered useless. Although more control is given to
+ the user if the assumptions made in continuous-voltage
+ mode do not reign true.
+
+Continuous Voltage: This mode uses the regulator's maximum and minimum
+ supplied voltages specified in the
+ regulator-{min,max}-microvolt properties to calculate
+ appropriate duty-cycle values. This allows for a much
+ more fine grained solution when compared with
+ voltage-table mode above. This solution does make an
+ assumption that a %50 duty-cycle value will cause the
+ regulator voltage to run at half way between the
+ supplied max_uV and min_uV values.
Required properties:
-- compatible: Should be "pwm-regulator"
-- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
-- voltage-table: voltage and duty table, include 2 members in each set of
- brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
+--------------------
+- compatible: Should be "pwm-regulator"
+
+- pwms: PWM specification (See: ../pwm/pwm.txt)
+
+Only required for Voltage Table Mode:
+- voltage-table: Voltage and Duty-Cycle table consisting of 2 cells
+ First cell is voltage in microvolts (uV)
+ Second cell is duty-cycle in percent (%)
+
+NB: To be clear, if voltage-table is provided, then the device will be used
+in Voltage Table Mode. If no voltage-table is provided, then the device will
+be used in Continuous Voltage Mode.

+TI Wakeup M3 Remoteproc Driver
+==============================
+
+The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+that cannot be controlled from the MPU. This CM3 processor requires a firmware
+binary to accomplish this. The wkup_m3 remoteproc driver handles the loading of
+the firmware and booting of the CM3.
+
+Wkup M3 Device Node:
+====================
+A wkup_m3 device node is used to represent the Wakeup M3 processor instance
+within the SoC. It is added as a child node of the parent interconnect bus
+(l4_wkup) through which it is accessible to the MPU.
+
+Required properties:
+--------------------
+- compatible: Should be one of,
+ "ti,am3352-wkup-m3" for AM33xx SoCs
+ "ti,am4372-wkup-m3" for AM43xx SoCs
+- reg: Should contain the address ranges for the two internal
+ memory regions, UMEM and DMEM. The parent node should
+ provide an appropriate ranges property for properly
+ translating these into bus addresses.
+- reg-names: Contains the corresponding names for the two memory
+ regions. These should be named "umem" & "dmem".
+- ti,hwmods: Name of the hwmod associated with the wkupm3 device.
+- ti,pm-firmware: Name of firmware file to be used for loading and
+ booting the wkup_m3 remote processor.
+
+Example:
+--------

+MediaTek SCPSYS
+===============
+
+The System Control Processor System (SCPSYS) has several power management
+related tasks in the system. The tasks include thermal measurement, dynamic
+voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
+The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
+domain control.
+
+The driver implements the Generic PM domain bindings described in
+power/power_domain.txt. It provides the power domains defined in
+include/dt-bindings/power/mt8173-power.h.
+
+Required properties:
+- compatible: Must be "mediatek,mt8173-scpsys"
+- #power-domain-cells: Must be 1
+- reg: Address range of the SCPSYS unit
+- infracfg: must contain a phandle to the infracfg controller
+- clock, clock-names: clocks according to the common clock binding.
+ The clocks needed "mm", "mfg", "venc" and "venc_lt".
+ These are the clocks which hardware needs to be enabled
+ before enabling certain power domains.
+
+Example:
+
+ scpsys: scpsys@10006000 {
+ #power-domain-cells = <1>;
+ compatible = "mediatek,mt8173-scpsys";
+ reg = <0 0x10006000 0 0x1000>;

+
+Controller Node
+---------------
+
+Required properties:
+- compatible : "allwinner,sun4i-a10-sram-controller"
+- reg : sram controller register offset + length
+
+SRAM nodes
+----------
+
+Each SRAM is described using the mmio-sram bindings documented in
+Documentation/devicetree/bindings/misc/sram.txt
+
+Each SRAM will have SRAM sections that are going to be handled by the
+SRAM controller as subnodes. These sections are represented following
+once again the representation described in the mmio-sram binding.
+
+The valid sections compatible are:
+ - allwinner,sun4i-a10-sram-a3-a4
+ - allwinner,sun4i-a10-sram-d
+
+Devices using SRAM sections
+---------------------------
+
+Some devices need to request to the SRAM controller to map an SRAM for
+their exclusive use.
+
+The relationship between such a device and an SRAM section is
+expressed through the allwinner,sram property, that will take a
+phandle and an argument.
+
+This valid values for this argument are:
+ - 0: CPU
+ - 1: Device

-** Samsung's usb 3.0 phy transceiver
-
-Starting exynso5250, Samsung's SoC have usb 3.0 phy transceiver
-which is used for controlling usb 3.0 phy for dwc3-exynos usb 3.0
-controllers across Samsung SOCs.
-
-Required properties:
-
-Exynos5250:
-- compatible : should be "samsung,exynos5250-usb3phy"
-- reg : base physical address of the phy registers and length of memory mapped
- region.
-- clocks: Clock IDs array as required by the controller.
-- clock-names: names of clocks correseponding to IDs in the clock property
- as requested by the controller driver.
-
-Optional properties:
-- #address-cells: should be '1' when usbphy node has a child node with 'reg'
- property.
-- #size-cells: should be '1' when usbphy node has a child node with 'reg'
- property.
-- ranges: allows valid translation between child's address space and parent's
- address space.
-
-- The child node 'usbphy-sys' to the node 'usbphy' is for the system controller
- interface for usb-phy. It should provide the following information required by
- usb-phy controller to control phy.
- - reg : base physical address of PHY_CONTROL registers.
- The size of this register is the total sum of size of all PHY_CONTROL
- registers that the SoC has. For example, the size will be
- '0x4' in case we have only one PHY_CONTROL register (e.g.
- OTHERS register in S3C64XX or USB_PHY_CONTROL register in S5PV210)
- and, '0x8' in case we have two PHY_CONTROL registers (e.g.
