+Freescale i.MX audio complex with WM8962 codec
+
+Required properties:
+- compatible : "fsl,imx-audio-wm8962"
+- 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 WM8962 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, WM8962 pins, and the jacks on the board:
+
+ Power supplies:
+ * Mic Bias
+
+ Board connectors:
+ * Mic Jack
+ * Headphone Jack
+ * Ext Spk
+
+- 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,imx6q-sabresd-wm8962",
+ "fsl,imx-audio-wm8962";
+ model = "wm8962-audio";
+ ssi-controller = <&ssi2>;
+ audio-codec = <&codec>;
+ audio-routing =
+ "Headphone Jack", "HPOUTL",
+ "Headphone Jack", "HPOUTR",
+ "Ext Spk", "SPKOUTL",
+ "Ext Spk", "SPKOUTR",
+ "MICBIAS", "AMIC",
+ "IN3R", "MICBIAS",
+ "DMIC", "MICBIAS",
+ "DMICDAT", "DMIC";
+ mux-int-port = <2>;
+ mux-ext-port = <3>;
+};
