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>

+TPS65090 regulators
+
+Required properties:
+- compatible: "ti,tps65090"
+- reg: I2C slave address
+- interrupts: the interrupt outputs of the controller
+- regulators: A node that houses a sub-node for each regulator within the
+ device. Each sub-node is identified using the node's name, with valid
+ values listed below. The content of each sub-node is defined by the
+ standard binding for regulators; see regulator.txt.
+ dcdc[1-3], fet[1-7] and ldo[1-2] respectively.
+- vsys[1-3]-supply: The input supply for DCDC[1-3] respectively.
+- infet[1-7]-supply: The input supply for FET[1-7] respectively.
+- vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively.
+
+Optional properties:
+- ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3.
+ If DCDCs are externally controlled then this property should be there.
+- "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3.
+ If DCDCs are externally controlled and if it is from GPIO then GPIO
+ number should be provided. If it is externally controlled and no GPIO
+ entry then driver will just configure this rails as external control
+ and will not provide any enable/disable APIs.
+- ti,overcurrent-wait: This is applicable to FET registers, which have a
+ poorly defined "overcurrent wait" field. If this property is present it
+ should be between 0 - 3. If this property isn't present we won't touch the
+ "overcurrent wait" field and we'll leave it to the BIOS/EC to deal with.
+
+Each regulator is defined using the standard binding for regulators.
+
+Example:
+
+ tps65090@48 {
+ compatible = "ti,tps65090";
+ reg = <0x48>;
+ interrupts = <0 88 0x4>;

+ infet2-supply = <&some_reg>;
+ infet3-supply = <&some_reg>;
+ infet4-supply = <&some_reg>;
+ infet5-supply = <&some_reg>;
+ infet6-supply = <&some_reg>;
+ infet7-supply = <&some_reg>;
+ vsys-l1-supply = <&some_reg>;
+ vsys-l2-supply = <&some_reg>;
