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.

+AK5386 Single-ended 24-Bit 192kHz delta-sigma ADC
+
+This device has no control interface.
+
+Required properties:
+
+  - compatible : "asahi-kasei,ak5386"
+
+Optional properties:
+
+  - reset-gpio : a GPIO spec for the reset/power down pin.
+		 If specified, it will be deasserted at probe time.
+  - va-supply : a regulator spec, providing 5.0V
+  - vd-supply : a regulator spec, providing 3.3V
+
+Example:
+
+spdif: ak5386@0 {
+	compatible = "asahi-kasei,ak5386";
+	reset-gpio = <&gpio0 23>;
+	va-supply = <&vdd_5v0_reg>;
+	vd-supply = <&vdd_3v3_reg>;
+};
