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.

+Freescale i.MX DRM master device
+================================
+
+The freescale i.MX DRM master device is a virtual device needed to list all
+IPU or other display interface nodes that comprise the graphics subsystem.
+
+Required properties:
+- compatible: Should be "fsl,imx-display-subsystem"
+- ports: Should contain a list of phandles pointing to display interface ports
+  of IPU devices
+
+example:
+
+display-subsystem {
+	compatible = "fsl,display-subsystem";
+	ports = <&ipu_di0>;
+};
+
+
+Freescale i.MX IPUv3
+====================
+
+Required properties:
+- compatible: Should be "fsl,<chip>-ipu"
+- reg: should be register base and length as documented in the
+  datasheet
+- interrupts: Should contain sync interrupt and error interrupt,
+  in this order.
+- resets: phandle pointing to the system reset controller and
+          reset line index, see reset/fsl,imx-src.txt for details
+Optional properties:
+- port@[0-3]: Port nodes with endpoint definitions as defined in
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
+  Ports 0 and 1 should correspond to CSI0 and CSI1,
+  ports 2 and 3 should correspond to DI0 and DI1, respectively.
+
+example:
+
+ipu: ipu@18000000 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "fsl,imx53-ipu";
+	reg = <0x18000000 0x080000000>;
+	interrupts = <11 10>;
+	resets = <&src 2>;
+
+	ipu_di0: port@2 {
+		reg = <2>;
+
+		ipu_di0_disp0: endpoint {
+			remote-endpoint = <&display_in>;
+		};
+	};
+};
+
+Parallel display support
+========================
+
+Required properties:
+- compatible: Should be "fsl,imx-parallel-display"
+Optional properties:
+- interface_pix_fmt: How this display is connected to the
+  display interface. Currently supported types: "rgb24", "rgb565", "bgr666"
+  and "lvds666".
+- edid: verbatim EDID data block describing attached display.
+- ddc: phandle describing the i2c bus handling the display data
+  channel
+- port: A port node with endpoint definitions as defined in
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+example:
+
+display@di0 {
+	compatible = "fsl,imx-parallel-display";
+	edid = [edid-data];
+	interface-pix-fmt = "rgb24";
+
+	port {
+		display_in: endpoint {
+			remote-endpoint = <&ipu_di0_disp0>;
+		};
+	};
+};
