* 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>;
};
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. */
};

* 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>;
};
