* 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>;

		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. */

	};
