+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>;
+       };
