+* 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:
+ - Machine Driver:
+ - stericsson,cpu-dai : Phandle to the CPU-side DAI
+ - stericsson,audio-codec : Phandle to the Audio CODEC
+
+Example:
+
+ sound {
+ compatible = "stericsson,snd-soc-mop500";
+
+ stericsson,cpu-dai = <&msp1 &msp3>;
+ stericsson,audio-codec = <&codec>;
+ };
+
+ msp1: msp at 80124000 {
+ compatible = "stericsson,ux500-msp-i2s";
+ reg = <0x80124000 0x1000>;
+ interrupts = <0 62 0x4>;
+ v-ape-supply = <&db8500_vape_reg>;
+ };
+
+ msp3: msp at 80125000 {
+ compatible = "stericsson,ux500-msp-i2s";
+ reg = <0x80125000 0x1000>;
+ interrupts = <0 62 0x4>;
+ v-ape-supply = <&db8500_vape_reg>;
+ };
+
+ codec: ab8500-codec {
+ compatible = "stericsson,ab8500-codec";
+ stericsson,earpeice-cmv = <950>; /* Units in mV. */
+ };
