+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>;- };

- codec: ab8500-codec {
compatible = "stericsson,ab8500-codec";stericsson,earpeice-cmv = <950>; /* Units in mV. */This parameter has nothing to do with the ASoC platform-driver. Some way or the other the earpiece-cmv should belong to the codec-driver. Also, this parameter was set in the previous patch as well?!
You know that this is just a documentation patch right?
It just shows how the pieces fit together. No settings will actually be read from here, it's just a .txt file used for reference.
Kind regards, Lee
