- ti,mcbsp: phandle for the McBSP node
- ti,codec: phandle for the twl4030 audio node
Optional properties:
- ti,mcbsp-voice: phandle for the McBSP node connected to the voice port of twl
- ti, jack-det-gpio: Jack detect GPIO
- 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.
If the routing is not provided all possible connection will be available
Available audio endpoints for the audio-routing table:
Board connectors:
* Headset Stereophone
* Earpiece Spk
* Handsfree Spk
* Ext Spk
* Main Mic
* Sub Mic
* Headset Mic
* Carkit Mic
* Digital0 Mic
* Digital1 Mic
* Line In
twl4030 pins:
* HSOL

* EARPIECE
* HFL
* HFR
* PREDRIVEL
* PREDRIVER
* CARKITL
* CARKITR
* MAINMIC
* SUBMIC
* HSMIC
