+* ux500 MSP (CPU-side Digital Audio Interface)
+
+Required properties:
+ - compatible :"stericsson,ux500-msp-i2s"
+ - reg : Physical base address and length of the device's registers.
+
+Optional properties:
+ - interrupts : The interrupt output from the device.
+ - interrupt-parent : The parent interrupt controller.
+ - <name>-supply : Phandle to the regulator <name> supply
+
+Example:
+
+ sound {
+ compatible = "stericsson,snd-soc-mop500";
+
+ stericsson,platform-pcm-dma = <&pcm>;
+ stericsson,cpu-dai = <&msp1 &msp3>;
