Device tree support for Davinci Machine driver When the board boots with device tree, the driver will receive card, codec, dai interface details (like the card name, DAPM routing map, phandle for the audio components described in the dts file, codec mclk speed). The card will be set up based on this information. Since the routing is provided via DT we can mark the card fully routed so core can take care of disconnecting the unused pins.

* Texas Instruments SoC audio setups with TLV320AIC3X Codec
|
|
|
|
Required properties:
|
|
- compatible : "ti,da830-evm-audio" : forDM365/DA8xx/OMAPL1x/AM33xx
|
|
- ti,model : The user-visible name of this sound complex.
|
|
- ti,audio-codec : The phandle of the TLV320AIC3x audio codec
|
|
- ti,mcasp-controller : The phandle of the McASP controller
|
|
- ti,codec-clock-rate : The Codec Clock rate (in Hz) applied to the Codec
|
|
- ti,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 for sources and
|
|
sinks are the codec's pins, and the jacks on the board:

* Headphone Jack
|
|

|
* Mic Jack
|
|
* Line In
