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>

+* Freescale IMX51 IOMUX Controller
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx51-iomuxc"
+- fsl,pins: two integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+ pin working on a specific function, CONFIG is the pad setting value like
+ pull-up for this pin. Please refer to imx51 datasheet for the valid pad
+ config settings.
+
+CONFIG bits definition:
+PAD_CTL_HVE (1 << 13)
+PAD_CTL_HYS (1 << 8)
+PAD_CTL_PKE (1 << 7)
+PAD_CTL_PUE (1 << 6)
+PAD_CTL_PUS_100K_DOWN (0 << 4)
+PAD_CTL_PUS_47K_UP (1 << 4)
+PAD_CTL_PUS_100K_UP (2 << 4)
+PAD_CTL_PUS_22K_UP (3 << 4)
+PAD_CTL_ODE (1 << 3)
+PAD_CTL_DSE_LOW (0 << 1)
+PAD_CTL_DSE_MED (1 << 1)
+PAD_CTL_DSE_HIGH (2 << 1)
+PAD_CTL_DSE_MAX (3 << 1)
+PAD_CTL_SRE_FAST (1 << 0)
+PAD_CTL_SRE_SLOW (0 << 0)
+
+Refer to imx51-pinfunc.h in device tree source folder for all available
+imx51 PIN_FUNC_ID.
