+Freescale i.MX audio complex with CS4271 or CS4272 codec
+
+Required properties:
+
+ - compatible : "fsl,imx-audio-cs427x"
+
+ - model : The user-visible name of this sound complex
+
+ - ssi-controller : The phandle of the i.MX SSI controller
+
+ - audio-codec : The phandle of the CS4271 audio codec
+
+ - audio-routing : A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the
+ connection's sink, the second being the connection's
+ source. Valid names could be power supplies, CS427x
+ pins, and the jacks on the board:
+
+ Board connectors:
+ * Mic Jack
+ * Headphone Jack
+
+ - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
+
+ - 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 = "fsl,imx6-rex-cs427x",
+ "fsl,imx-audio-cs427x";
+ model = "audio-cs427x";
+ ssi-controller = <&ssi1>;
+ audio-codec = <&cs4271>;
+ audio-routing =
+ "Mic Jack", "AINA",
+ "Mic Jack", "AINB",
+ "Headphone Jack", "AOUTA+",
+ "Headphone Jack", "AOUTA-",
+ "Headphone Jack", "AOUTB+",
+ "Headphone Jack", "AOUTB-";
+ mux-int-port = <1>;
+ mux-ext-port = <3>;
