* Texas Instruments SoC with twl4030 based audio setups
Required properties:
- compatible: "ti,omap-twl4030"
- ti,model: Name of the sound card (for example "omap3beagle")
- ti,mcbsp: phandle for the McBSP node
- ti,codec: phandle for the twl4030 audio node
Example:
sound {
compatible = "ti,omap-twl4030";
ti,model = "omap3beagle";
ti,mcbsp = <&mcbsp2>;
ti,codec = <&twl_audio>;
