+* 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. */
+ };
