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>

+Renesas Electronics USBHS driver
+
+Required properties:
+ - compatible: Must contain one of the following:
+ - "renesas,usbhs-r8a7790"
+ - "renesas,usbhs-r8a7791"
+ - reg: Base address and length of the register for the USBHS
+ - interrupts: Interrupt specifier for the USBHS
+ - clocks: A list of phandle + clock specifier pairs
+
+Optional properties:
+ - renesas,buswait: Integer to use BUSWAIT register
+ - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
+ function should be enabled
+ - phys: phandle + phy specifier pair
+ - phy-names: must be "usb"
+ - dmas: Must contain a list of references to DMA specifiers.
+ - dma-names : named "ch%d", where %d is the channel number ranging from zero
+ to the number of channels (DnFIFOs) minus one.
+
+Example:
+ usbhs: usb@e6590000 {
+ compatible = "renesas,usbhs-r8a7790";
+ reg = <0 0xe6590000 0 0x100>;
+ interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
+ };
