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.

+Binding for Maxim MAX77802 regulators
+
+This is a part of device tree bindings of MAX77802 multi-function device.
+More information can be found in bindings/mfd/max77802.txt file.
+
+The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- regulators : The regulators of max77802 have to be instantiated
+  under subnode named "regulators" using the following format.
+
+	regulator-name {
+		standard regulator constraints....
+	};
+	refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+The regulator node name should be initialized with a string to get matched
+with their hardware counterparts as follow. The valid names are:
+
+	-LDOn 	:	for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
+			and 32-35.
+			example: LDO1, LDO2, LDO35.
+	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 10.
+			example: BUCK1, BUCK5, BUCK10.
+
+The max77802 regulator supports two different operating modes: Normal and Low
+Power Mode. Some regulators support the modes to be changed at startup or by
+the consumers during normal operation while others only support to change the
+mode during system suspend. The standard regulator suspend states binding can
+be used to configure the regulator operating mode.
+
+The regulators that support the standard "regulator-initial-mode" property,
+changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
+
+The possible values for "regulator-initial-mode" and "regulator-mode" are:
+	1: Normal regulator voltage output mode.
+	3: Low Power which reduces the quiescent current down to only 1uA
+
+The list of valid modes are defined in the dt-bindings/clock/maxim,max77802.h
+header and can be included by device tree source files.
+
+The standard "regulator-mode" property can only be used for regulators that
+support changing their mode to Low Power Mode during suspend. These regulators
+are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
+been enabled for the given suspend state using "regulator-on-in-suspend" and
+has not been disabled for that state using "regulator-off-in-suspend".
+
+Example:
+
+	max77802@09 {
+		compatible = "maxim,max77802";
+		interrupt-parent = <&wakeup_eint>;
+		interrupts = <26 0>;
+		reg = <0x09>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		regulators {
+			ldo1_reg: LDO1 {
+				regulator-name = "vdd_1v0";
+				regulator-min-microvolt = <1000000>;
+				regulator-max-microvolt = <1000000>;
+				regulator-always-on;
+				regulator-initial-mode = <MAX77802_OPMODE_LP>;
+			};
+
+			ldo11_reg: LDO11 {
+				regulator-name = "vdd_ldo11";
+				regulator-min-microvolt = <1900000>;
+				regulator-max-microvolt = <1900000>;
+				regulator-always-on;
+				regulator-state-mem {
+					regulator-on-in-suspend;
+					regulator-mode = <MAX77802_OPMODE_LP>;
+				};
+			};
+
+			buck1_reg: BUCK1 {
+				regulator-name = "vdd_mif";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-always-on;
+				regulator-boot-on;
+			};
