+Device Tree bindings for the Armada 370 DB audio
+================================================
+
+These Device Tree bindings are used to describe the audio complex
+found on the Armada 370 DB platform.
+
+Mandatory properties:
+
+ * compatible: must be "marvell,a370db-audio"
+
+ * marvell,audio-controller: a phandle that points to the audio
+ controller of the Armada 370 SoC.
+
+ * marvell,audio-codec: a phandle that points to the analog audio
+ codec connected to the Armada 370 SoC.
+
+Example:
+
+ sound {
+ compatible = "marvell,a370db-audio";
+ marvell,audio-controller = <&audio_controller>;
+ marvell,audio-codec = <&audio_codec>;
+ status = "okay";
+ };
