    +* ux500 Audio Driver and ab8500 Audio CODEC
    +
    +Required properties:
    + - compatible:
    + - Machine Driver : "stericsson,snd-soc-mop500"
    + - CPU-side DAI : "stericsson,ux500-msp-i2s"
    + - DMA (platform) : "stericsson,ux500-pcm"
    + - Audio CODEC : "stericsson,ab8500-codec"
    +
    +Optional properties:
    + - reg : Physical base address and length of the device's registers.
    + - interrupts : The interrupt outputs from the device.
    + - interrupt-parent : The parent interrupt controller.
    + - <name>-supply : Phandle to the regulator <name> supply
    +
    +Non-standard properties:
    + - Machine Driver:
    + - stericsson,platform-pcm-dma : Phandle to the DMA (platform) node
    + - stericsson,cpu-dai : Phandle to the CPU-side DAI
    + - stericsson,audio-codec : Phandle to the Audio CODEC
    + - CPU-side DAI:
    + - stericcson,use-pinctrl : Indicates whether an MSP port has pinctrl support
    + - Audio CODEC:
    + - stericsson,amic[1|2]-type-single-ended : Single-ended Analoge Mic (default: differential)
    + - stericsson,amic1a-bias-vamic2 : Analoge Mic wishes to use a non-standard Vamic
    + - stericsson,amic1b-bias-vamic2 : Analoge Mic wishes to use a non-standard Vamic
    + - stericsson,amic2-bias-vamic1 : Analoge Mic wishes to use a non-standard Vamic
    + - stericsson,earpeice-cmv : Earpeice voltage (only: 950 | 1100 | 1270 | 1580)
    +
    +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>;
    + stericcson,use-pinctrl;
    + };
    +
    + 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. */
    + };
