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:

    Prepare v4.1.3-rt3

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+Binding for the LTC2952 PowerPath controller
+
+This chip is used to externally trigger a system shut down. Once the trigger has
+been sent, the chip's watchdog has to be reset to gracefully shut down.
+A full powerdown can be triggered via the kill signal.
+
+Required properties:
+
+- compatible:		Must contain: "lltc,ltc2952"
+- watchdog-gpios:	phandle + gpio-specifier for the GPIO connected to the
+			chip's watchdog line
+- kill-gpios:		phandle + gpio-specifier for the GPIO connected to the
+			chip's kill line
+
+Optional properties:
+- trigger-gpios:	phandle + gpio-specifier for the GPIO connected to the
+			chip's trigger line. If this property is not set, the
+			trigger function is ignored and the chip is kept alive
+			until an explicit kill signal is received
+
+Example:
+
+ltc2952 {
+	compatible = "lltc,ltc2952";
+
+	trigger-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
+	watchdog-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
+	kill-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
+};
