- model : The user-visible name of this sound complex
- ssi-controller : The phandle of the i.MX SSI controller
- audio-codec : The phandle of the SGTL5000 audio codec
- audio-routing : A list of the 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. Valid names could be power
supplies, SGTL5000 pins, and the jacks on the board:
Power supplies:
* Mic Bias
SGTL5000 pins:
* MIC_IN
* LINE_IN
* HP_OUT
* LINE_OUT
Board connectors:
* Mic Jack
* Line In Jack
* Headphone Jack
* Line Out Jack
* Ext Spk
