Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+Analog Devices ADAU1701
+
+Required properties:
+
+ - compatible: Should contain "adi,adau1701"
+ - reg: The i2c address. Value depends on the state of ADDR0
+ and ADDR1, as wired in hardware.
+
+Optional properties:
+
+ - reset-gpio: A GPIO spec to define which pin is connected to the
+ chip's !RESET pin. If specified, the driver will
+ assert a hardware reset at probe time.
+ - adi,pll-mode-gpios: An array of two GPIO specs to describe the GPIOs
+ the ADAU's PLL config pins are connected to.
+ The state of the pins are set according to the
+ configured clock divider on ASoC side before the
+ firmware is loaded.
+ - adi,pin-config: An array of 12 numerical values selecting one of the
+ pin configurations as described in the datasheet,
+ table 53. Note that the value of this property has
+ to be prefixed with '/bits/ 8'.
+
+Examples:
+
+ i2c_bus {

+For required properties on SPI, please consult

+ - cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag
+ is enabled.
+ - cirrus,enable-soft-reset:
+ The CS4271 requires its LRCLK and MCLK to be stable before its RESET
+ line is de-asserted. That also means that clocks cannot be changed
+ without putting the chip back into hardware reset, which also requires
+ a complete re-initialization of all registers.
+
+ One (undocumented) workaround is to assert and de-assert the PDN bit
+ in the MODE2 register. This workaround can be enabled with this DT
+ property.
+
+ Note that this is not needed in case the clocks are stable
+ throughout the entire runtime of the codec.

+
+Required are also ac97 link bindings if ac97 is used. See

+bindings.
+
+Optional properties:
+- codec-handle: Phandle to a 'codec' node that defines an audio
+ codec connected to this SSI. This node is typically
+ a child of an I2C or other control node.
+- fsl,fiq-stream-filter: Bool property. Disabled DMA and use FIQ instead to
+ filter the codec stream. This is necessary for some boards
+ where an incompatible codec is connected to this SSI, e.g.
+ on pca100 and pcm043.
+- dmas: Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names: Two dmas have to be defined, "tx" and "rx", if fsl,imx-fiq
+ is not defined.
+- fsl,mode: The operating mode for the AC97 interface only.
+ "ac97-slave" - AC97 mode, SSI is clock slave
+ "ac97-master" - AC97 mode, SSI is clock master
+
+Child 'codec' node required properties:
+- compatible: Compatible list, contains the name of the codec
+
+Child 'codec' node optional properties:
+- clock-frequency: The frequency of the input clock, which typically comes
+ from an on-board dedicated oscillator.
+
+Notes on fsl,playback-dma and fsl,capture-dma:
+
+On SOCs that have an SSI, specific DMA channels are hard-wired for playback
+and capture. On the MPC8610, for example, SSI1 must use DMA channel 0 for
+playback and DMA channel 1 for capture. SSI2 must use DMA channel 2 for
+playback and DMA channel 3 for capture. The developer can choose which
+DMA controller to use, but the channels themselves are hard-wired. The
+purpose of these two properties is to represent this hardware design.
+
+The device tree nodes for the DMA channels that are referenced by
+"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
+"fsl,ssi-dma-channel". The SOC-specific compatible string (e.g.
+"fsl,mpc8610-dma-channel") can remain. If these nodes are left as
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
+drivers (fsldma) will attempt to use them, and it will conflict with the
+sound drivers.

+Freescale Generic ASoC Sound Card with ASRC support
+
+The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
+SoCs connecting with external CODECs.
+
+The idea of this generic sound card is a bit like ASoC Simple Card. However,
+for Freescale SoCs (especially those released in recent years), most of them
+have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
+this is a specific feature that might be painstakingly controlled and merged
+into the Simple Card.
+
+So having this generic sound card allows all Freescale SoC users to benefit
+from the simplification of a new card support and the capability of the wide
+sample rates support through ASRC.
+
+Note: The card is initially designed for those sound cards who use I2S and
+ PCM DAI formats. However, it'll be also possible to support those non
+ I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long
+ as the driver has been properly upgraded.
+
+
+The compatible list for this generic sound card currently:
+ "fsl,imx-audio-cs42888"
+
+ "fsl,imx-audio-wm8962"
+ (compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
+
+ "fsl,imx-audio-sgtl5000"
+ (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
+
+Required properties:
+
+ - compatible : Contains one of entries in the compatible list.
+
+ - model : The user-visible name of this sound complex
+
+ - audio-cpu : The phandle of an CPU DAI controller
+
+ - audio-codec : The phandle of an audio codec
+
+ - audio-routing : A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the
+ connection's sink, the second being the connection's
+ source. There're a few pre-designed board connectors:
+ * Line Out Jack
+ * Line In Jack
+ * Headphone Jack
+ * Mic Jack
+ * Ext Spk
+ * AMIC (stands for Analog Microphone Jack)
+ * DMIC (stands for Digital Microphone Jack)
+
+ Note: The "Mic Jack" and "AMIC" are redundant while
+ coexsiting in order to support the old bindings
+ of wm8962 and sgtl5000.
+
+Optional properties:
+
+ - audio-asrc : The phandle of ASRC. It can be absent if there's no
+ need to add ASRC support via DPCM.
+
+Example:
+sound-cs42888 {
+ compatible = "fsl,imx-audio-cs42888";
+ model = "cs42888-audio";
+ audio-cpu = <&esai>;
+ audio-asrc = <&asrc>;
+ audio-codec = <&cs42888>;
+ audio-routing =

+Freescale Synchronous Audio Interface (SAI).
+
+The SAI is based on I2S module that used communicating with audio codecs,
+which provides a synchronous audio interface that supports fullduplex
+serial interfaces with frame synchronization such as I2S, AC97, TDM, and
+codec/DSP interfaces.
+
+Required properties:
+
+ - compatible : Compatible list, contains "fsl,vf610-sai" or
+ "fsl,imx6sx-sai".
+
+ - reg : Offset and length of the register set for the device.
+
+ - clocks : Must contain an entry for each entry in clock-names.
+
+ - clock-names : Must include the "bus" for register access and
+ "mclk1", "mclk2", "mclk3" for bit clock and frame
+ clock providing.
+ - dmas : Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+
+ - dma-names : Two dmas have to be defined, "tx" and "rx".
+
+ - pinctrl-names : Must contain a "default" entry.
+
+ - pinctrl-NNN : One property must exist for each entry in
+ pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
+ for details of the property values.
+
+ - big-endian : Boolean property, required if all the FTM_PWM
+ registers are big-endian rather than little-endian.
+
+ - lsb-first : Configures whether the LSB or the MSB is transmitted
+ first for the fifo data. If this property is absent,
+ the MSB is transmitted first as default, or the LSB
+ is transmitted first.
+
+ - fsl,sai-synchronous-rx: This is a boolean property. If present, indicating
+ that SAI will work in the synchronous mode (sync Tx
+ with Rx) which means both the transimitter and the
+ receiver will send and receive data by following
+ receiver's bit clocks and frame sync clocks.
+
+ - fsl,sai-asynchronous: This is a boolean property. If present, indicating
+ that SAI will work in the asynchronous mode, which
+ means both transimitter and receiver will send and
+ receive data by following their own bit clocks and
+ frame sync clocks separately.
+
+Note:
+- If both fsl,sai-asynchronous and fsl,sai-synchronous-rx are absent, the
+ default synchronous mode (sync Rx with Tx) will be used, which means both
+ transimitter and receiver will send and receive data by following clocks
+ of transimitter.
+- fsl,sai-asynchronous and fsl,sai-synchronous-rx are exclusive.
+
+Example:
+sai2: sai@40031000 {
+ compatible = "fsl,vf610-sai";
+ reg = <0x40031000 0x1000>;
+ pinctrl-names = "default";

+These devices support both I2C and SPI (configured with pin strapping
+on the board).
+
+Required properties:
+
+ - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141" or
+ "ti,pcm5142"
+
+ - reg : the I2C address of the device for I2C, the chip select
+ number for SPI.
+
+ - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
+ device, as covered in bindings/regulator/regulator.txt
+
+Optional properties:
+
+ - clocks : A clock specifier for the clock connected as SCLK. If this
+ is absent the device will be configured to clock from BCLK. If pll-in
+ and pll-out are specified in addition to a clock, the device is
+ configured to accept clock input on a specified gpio pin.
+
+ - pll-in, pll-out : gpio pins used to connect the pll using <1>
+ through <6>. The device will be configured for clock input on the
+ given pll-in pin and PLL output on the given pll-out pin. An
+ external connection from the pll-out pin to the SCLK pin is assumed.
+
+Examples:
+
+ pcm5122: pcm5122@4c {
+ compatible = "ti,pcm5122";
+ reg = <0x4c>;
+
+ AVDD-supply = <&reg_3v3_analog>;

+* Samsung I2S controller
+
+Required SoC Specific Properties:
+
+- compatible : should be one of the following.
+ - samsung,s3c6410-i2s: for 8/16/24bit stereo I2S.
+ - samsung,s5pv210-i2s: for 8/16/24bit multichannel(5.1) I2S with
+ secondary fifo, s/w reset control and internal mux for root clk src.
+ - samsung,exynos5420-i2s: for 8/16/24bit multichannel(5.1) I2S for
+ playback, sterio channel capture, secondary fifo using internal
+ or external dma, s/w reset control, internal mux for root clk src
+ and 7.1 channel TDM support for playback. TDM (Time division multiplexing)
+ is to allow transfer of multiple channel audio data on single data line.
+ - samsung,exynos7-i2s: with all the available features of exynos5 i2s,
+ exynos7 I2S has 7.1 channel TDM support for capture, secondary fifo
+ with only external dma and more no.of root clk sampling frequencies.
+ - samsung,exynos7-i2s1: I2S1 on previous samsung platforms supports
+ stereo channels. exynos7 i2s1 upgraded to 5.1 multichannel with
+ slightly modified bit offsets.
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- dmas: list of DMA controller phandle and DMA request line ordered pairs.
+- dma-names: identifier string for each DMA request line in the dmas property.
+ These strings correspond 1:1 with the ordered pairs in dmas.
+- clocks: Handle to iis clock and RCLK source clk.
+- clock-names:
+ i2s0 uses some base clks from CMU and some are from audio subsystem internal
+ clock controller. The clock names for i2s0 should be "iis", "i2s_opclk0" and
+ "i2s_opclk1" as shown in the example below.
+ i2s1 and i2s2 uses clocks from CMU. The clock names for i2s1 and i2s2 should
+ be "iis" and "i2s_opclk0".
+ "iis" is the i2s bus clock and i2s_opclk0, i2s_opclk1 are sources of the root
+ clk. i2s0 has internal mux to select the source of root clk and i2s1 and i2s2
+ doesn't have any such mux.
+- #clock-cells: should be 1, this property must be present if the I2S device
+ is a clock provider in terms of the common clock bindings, described in
+ ../clock/clock-bindings.txt.
+- clock-output-names: from the common clock bindings, names of the CDCLK
+ I2S output clocks, suggested values are "i2s_cdclk0", "i2s_cdclk1",
+ "i2s_cdclk3" for the I2S0, I2S1, I2S2 devices recpectively.
+
+There are following clocks available at the I2S device nodes:
+ CLK_I2S_CDCLK - the CDCLK (CODECLKO) gate clock,
+ CLK_I2S_RCLK_PSR - the RCLK prescaler divider clock (corresponding to the
+ IISPSR register),
+ CLK_I2S_RCLK_SRC - the RCLKSRC mux clock (corresponding to RCLKSRC bit in
+ IISMOD register).
+
+Refer to the SoC datasheet for availability of the above clocks.
+The CLK_I2S_RCLK_PSR and CLK_I2S_RCLK_SRC clocks are usually only available
+in the IIS Multi Audio Interface (I2S0).
+Note: Old DTs may not have the #clock-cells, clock-output-names properties
+and then not use the I2S node as a clock supplier.
+
+Optional SoC Specific Properties:
+
+- samsung,idma-addr: Internal DMA register base address of the audio
+ sub system(used in secondary sound source).
+- pinctrl-0: Should specify pin control groups used for this controller.
+- pinctrl-names: Should contain only one value - "default".
+
+
+Example:
+
+i2s0: i2s@03830000 {
+ compatible = "samsung,s5pv210-i2s";

+ properties and the CPU and CODEC
+ sub-nodes. This container may be
+ omitted when the card has only one

+
+Dai-link subnode properties and subnodes:
+
+If dai-link subnode is omitted and the subnode properties are directly
+under "sound"-node the subnode property and subnode names have to be
+prefixed with "simple-audio-card,"-prefix.
+
+Required dai-link subnodes:
+
+- cpu : CPU sub-node
+- codec : CODEC sub-node
+
+Optional dai-link subnode properties:
+
+- format : CPU/CODEC common audio format.
+ "i2s", "right_j", "left_j" , "dsp_a"
+ "dsp_b", "ac97", "pdm", "msb", "lsb"

+ phandle to a cpu or codec subnode.
+- bitclock-inversion : bool property. Add this if the
+ dai-link uses bit clock inversion.
+- frame-inversion : bool property. Add this if the
+ dai-link uses frame clock inversion.
+
+For backward compatibility the frame-master and bitclock-master
+properties can be used as booleans in codec subnode to indicate if the

+should be no dai-link node, the same properties should not be present
+at sound-node level, and the bitclock-inversion and frame-inversion
+properties should also be placed in the codec node if needed.
+
+Required CPU/CODEC subnodes properties:
+
+- sound-dai : phandle and port of CPU/CODEC
+
+Optional CPU/CODEC subnodes properties:
+
+- dai-tdm-slot-num : Please refer to tdm-slot.txt.
+- dai-tdm-slot-width : Please refer to tdm-slot.txt.
+- clocks / system-clock-frequency : specify subnode's clock if needed.
+ it can be specified via "clocks" if system has
+ clock node (= common clock), or "system-clock-frequency"
+ (if system doens't support common clock)
+ If a clock is specified, it is
+ enabled with clk_prepare_enable()
+ in dai startup() and disabled with

+WM8962 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+ - compatible : "wlf,wm8962"
+
+ - reg : the I2C address of the device.
+
+Optional properties:
+ - spk-mono: This is a boolean property. If present, the SPK_MONO bit
+ of R51 (Class D Control 2) gets set, indicating that the speaker is
+ in mono mode.
+
+ - mic-cfg : Default register value for R48 (Additional Control 4).
+ If absent, the default should be the register default.
+
+ - gpio-cfg : A list of GPIO configuration register values. The list must
+ be 6 entries long. If absent, no configuration of these registers is
+ performed. And note that only the value within [0x0, 0xffff] is valid.
+ Any other value is regarded as setting the GPIO register by its reset
+ value 0x0.

+WM1811/WM8994/WM8958 audio CODEC
+
+These devices support both I2C and SPI (configured with pin strapping
+on the board).
+
+Required properties:
+
+ - compatible : One of "wlf,wm1811", "wlf,wm8994" or "wlf,wm8958".
+
+ - reg : the I2C address of the device for I2C, the chip select
+ number for SPI.
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+ - #gpio-cells : Must be 2. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+
+ - AVDD2-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply, CPVDD-supply,
+ SPKVDD1-supply, SPKVDD2-supply : power supplies for the device, as covered
+ in Documentation/devicetree/bindings/regulator/regulator.txt
+
+Optional properties:
+
+ - interrupts : The interrupt line the IRQ signal for the device is
+ connected to. This is optional, if it is not connected then none
+ of the interrupt related properties should be specified.
+ - interrupt-controller : These devices contain interrupt controllers
+ and may provide interrupt services to other devices if they have an
+ interrupt line connected.
+ - interrupt-parent : The parent interrupt controller.
+ - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
+ The first cell is the IRQ number.
+ The second cell is the flags, encoded as the trigger masks from
+ Documentation/devicetree/bindings/interrupts.txt
+
+ - clocks : A list of up to two phandle and clock specifier pairs
+ - clock-names : A list of clock names sorted in the same order as clocks.
+ Valid clock names are "MCLK1" and "MCLK2".
+
+ - wlf,gpio-cfg : A list of GPIO configuration register values. If absent,
+ no configuration of these registers is performed. If any value is
+ over 0xffff then the register will be left as default. If present 11
+ values must be supplied.
+
+ - wlf,micbias-cfg : Two MICBIAS register values for WM1811 or
+ WM8958. If absent the register defaults will be used.
+
+ - wlf,ldo1ena : GPIO specifier for control of LDO1ENA input to device.
+ - wlf,ldo2ena : GPIO specifier for control of LDO2ENA input to device.
+
+ - wlf,lineout1-se : If present LINEOUT1 is in single ended mode.
+ - wlf,lineout2-se : If present LINEOUT2 is in single ended mode.
+
+ - wlf,lineout1-feedback : If present LINEOUT1 has common mode feedback
+ connected.
+ - wlf,lineout2-feedback : If present LINEOUT2 has common mode feedback
+ connected.
+
+ - wlf,ldoena-always-driven : If present LDOENA is always driven.
