+Freescale i.MX audio complex with WM8960 codec
+
+Required properties:
+
+  - compatible         : "fsl,imx-audio-wm8960", "fsl,imx7d-evk-wm8960"
+
+  - model              : The user-visible name of this sound complex
+
+  - cpu-dai            : The phandle of CPU DAI
+
+  - audio-codec                : The phandle of the WM8960 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, WM8960
+                         pins, and the jacks on the board:
+
+                         Power supplies:
+                          * Mic Bias
+
+                         Board connectors:
+                          * Mic Jack
+                          * Headphone Jack
+                          * Ext Spk
+
+Optional properties:
+- hp-det-gpios : The gpio pin to detect plug in/out event that happens to
+  Headphone jack.
+- mic-det-gpios: The gpio pin to detect plug in/out event that happens to
+  Microphone jack.
