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>

+ AM33xx MUSB
+~~~~~~~~~~~~~~~
+- compatible: ti,am33xx-usb
+- reg: offset and length of the usbss register sets
+- ti,hwmods : must be "usb_otg_hs"
+
+The glue layer contains multiple child nodes. It is required the have
+at least a control module node, USB node and a PHY node. The second USB
+node and its PHY node is optional. The DMA node is also optional.
+
+Reset module
+~~~~~~~~~~~~
+- compatible: ti,am335x-usb-ctrl-module
+- reg: offset and length of the "USB control registers" in the "Control
+ Module" block. A second offset and length for the USB wake up control
+ in the same memory block.
+- reg-names: "phy_ctrl" for the "USB control registers" and "wakeup" for
+ the USB wake up control register.
+
+USB PHY
+~~~~~~~
+compatible: ti,am335x-usb-phy
+reg: offset and length of the "USB PHY" register space
+ti,ctrl_mod: reference to the "reset module" node
+reg-names: phy
+The PHY should have a "phy" alias numbered properly in the alias
+node.
+
+USB
+~~~
+- compatible: ti,musb-am33xx
+- reg: offset and length of "USB Controller Registers", and offset and
+ length of "USB Core" register space.
+- reg-names: control for the ""USB Controller Registers" and "mc" for
+ "USB Core" register space
+- interrupts: USB interrupt number
+- interrupt-names: mc
+- dr_mode: Should be one of "host", "peripheral" or "otg".
+- mentor,multipoint: Should be "1" indicating the musb controller supports
+ multipoint. This is a MUSB configuration-specific setting.
+- mentor,num-eps: Specifies the number of endpoints. This is also a
+ MUSB configuration-specific setting. Should be set to "16"
+- mentor,ram-bits: Specifies the ram address size. Should be set to "12"
+- mentor,power: Should be "500". This signifies the controller can supply up to
+ 500mA when operating in host mode.
+- phys: reference to the USB phy
+- dmas: specifies the dma channels
+- dma-names: specifies the names of the channels. Use "rxN" for receive
+ and "txN" for transmit endpoints. N specifies the endpoint number.
+
+The controller should have an "usb" alias numbered properly in the alias
+node.
+
+DMA
+~~~
+- compatible: ti,am3359-cppi41
+- reg: offset and length of the following register spaces: USBSS, USB
+ CPPI DMA Controller, USB CPPI DMA Scheduler, USB Queue Manager
+- reg-names: glue, controller, scheduler, queuemgr
+- #dma-cells: should be set to 2. The first number represents the
+ endpoint number (0 … 14 for endpoints 1 … 15 on instance 0 and 15 … 29
+ for endpoints 1 … 15 on instance 1). The second number is 0 for RX and
+ 1 for TX transfers.
+- #dma-channels: should be set to 30 representing the 15 endpoints for
+ each USB instance.

+ST DWC3 glue logic
+
+This file documents the parameters for the dwc3-st driver.

+STiH407 based platforms.
+
+Required properties:
+ - compatible : must be "st,stih407-dwc3"
+ - reg : glue logic base address and USB syscfg ctrl register offset

+ encompasses the glue registers
+ - resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the powerdown and softreset lines of the usb3 IP

+Freescale SOC USB controllers

+Practice : Universal Serial Bus" with the following modifications
+and additions :
+
+Required properties :
+ - compatible : Should be "fsl-usb2-mph" for multi port host USB
+ controllers, or "fsl-usb2-dr" for dual role USB controllers
+ or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
+ Wherever applicable, the IP version of the USB controller should
+ also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
+ - phy_type : For multi port host USB controllers, should be one of
+ "ulpi", or "serial". For dual role USB controllers, should be
+ one of "ulpi", "utmi", "utmi_wide", or "serial".
+ - reg : Offset and length of the register set for the device
+ - port0 : boolean; if defined, indicates port0 is connected for
+ fsl-usb2-mph compatible controllers. Either this property or
+ "port1" (or both) must be defined for "fsl-usb2-mph" compatible

+ fsl-usb2-mph compatible controllers. Either this property or
+ "port0" (or both) must be defined for "fsl-usb2-mph" compatible
+ controllers.
+ - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
+ controllers. Can be "host", "peripheral", or "otg". Default to
+ "host" if not defined for backward compatibility.
+
+Recommended properties :
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+Optional properties :
+ - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
+ port power polarity of internal PHY signal DRVVBUS is inverted.
+ - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
+ the PWR_FAULT signal polarity is inverted.
+
+Example multi port host USB controller device node :

+The Samsung's usb 2.0 phy transceiver is used for controlling
+usb 2.0 phy for s3c-hsotg as well as ehci-s5p and ohci-exynos
+usb controllers across Samsung SOCs.
+TODO: Adding the PHY binding with controller(s) according to the under
+development generic PHY driver.
+
+Required properties:

+- compatible: Should be "smsc,usb3503" or "smsc,usb3503a".
+
+Optional properties:
+- reg: Specifies the i2c slave address, it is required and should be 0x08
+ if I2C is used.
+- connect-gpios: Should specify GPIO for connect.
+- disabled-ports: Should specify the ports unused.
+ '1' or '2' or '3' are available for this property to describe the port
+ number. 1~3 property values are possible to be described.
+ Do not describe this property if all ports have to be enabled.
+- intn-gpios: Should specify GPIO for interrupt.
+- reset-gpios: Should specify GPIO for reset.
+- initial-mode: Should specify initial mode.
+ (1 for HUB mode, 2 for STANDBY mode)
+- refclk: Clock used for driving REFCLK signal (optional, if not provided
+ the driver assumes that clock signal is always available, its
+ rate is specified by REF_SEL pins and a value from the primary
+ reference clock frequencies table is used)
+- refclk-frequency: Frequency of the REFCLK signal as defined by REF_SEL
+ pins (optional, if not provided, driver will not set rate of the
+ REFCLK signal and assume that a value from the primary reference
+ clock frequencies table is used)
+
+Examples:
+ usb3503@08 {
+ compatible = "smsc,usb3503";
+ reg = <0x08>;
+ connect-gpios = <&gpx3 0 1>;
+ disabled-ports = <2 3>;

+ initial-mode = <1>;
