| * Texas Instruments OMAP4+ and twl6040 based audio setups
|
| Required properties:
| - compatible: "ti,abe-twl6040"
| - ti,model: Name of the sound card ( for example "SDP4430")
| - ti,mclk-freq: MCLK frequency for HPPLL operation
| - ti,mcpdm: phandle for the McPDM node
| - ti,twl6040: phandle for the twl6040 core node
| - ti,audio-routing: List of connections between audio components.
| Each entry is a pair of strings, the first being the connection's sink,
| the second being the connection's source.
|
| Optional properties:
| - ti,dmic: phandle for the OMAP dmic node if the machine have it connected
| - ti,jack-detection: Need to be present if the board capable to detect jack
| insertion, removal.
