+* MOP500 Audio Machine Driver
+
+This node is responsible for linking together all ux500 Audio Driver components.
+
+Required properties:
+ - compatible              : "stericsson,snd-soc-mop500"
+
+Non-standard properties:
+ - stericsson,cpu-dai      : Phandle to the CPU-side DAI
+ - stericsson,audio-codec  : Phandle to the Audio CODEC
+ - stericsson,card-name    : Over-ride default card name
+
+Example:
+
+       sound {
+               compatible = "stericsson,snd-soc-mop500";
+
+               stericsson,cpu-dai = <&msp1 &msp3>;
+               stericsson,audio-codec = <&codec>;
+       };
+
