| * 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. |
