+* 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.
+ - <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>;
+		stericsson,audio-codec = <&codec>;
+	};
+
+	pcm: ux500-pcm {
+		compatible = "stericsson,ux500-pcm";
+	};
+
+	msp1: msp@80124000 {
+		compatible = "stericsson,ux500-msp-i2s";
+		reg = <0x80124000 0x1000>;
+		interrupts = <0 62 0x4>;
+		v-ape-supply = <&db8500_vape_reg>;
+	};
+
+	msp3: msp@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. */
+	};
