+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";
