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:

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

+Audio complex for Eukrea boards with tlv320aic23 codec.
+
+Required properties:
+
+  - compatible		: "eukrea,asoc-tlv320"
+
+  - eukrea,model	: The user-visible name of this sound complex.
+
+  - ssi-controller	: The phandle of the SSI controller.
+
+  - fsl,mux-int-port	: The internal port of the i.MX audio muxer (AUDMUX).
+
+  - fsl,mux-ext-port	: The external port of the i.MX audio muxer.
+
+Note: The AUDMUX port numbering should start at 1, which is consistent with
+hardware manual.
+
+Example:
+
+	sound {
+		compatible = "eukrea,asoc-tlv320";
+		eukrea,model = "imx51-eukrea-tlv320aic23";
+		ssi-controller = <&ssi2>;
+		fsl,mux-int-port = <2>;
+		fsl,mux-ext-port = <3>;
+	};
