The referenced clock is used to get codec clock rate and the clock is disabled and enabled in startup and shutdown snd_soc_ops call backs. The change is also documented in DT bindigs document.

* 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,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:
|
|
|
|
Optional properties:
|
|
- ti,codec-clock-rate : The Codec Clock rate (in Hz) applied to the Codec.
|
|
- clocks : Reference to the master clock
|
|
- clock-names : The clock should be named "mclk"
|
|
- Either codec-clock-rate or the codec-clock reference has to be defined. If
|
|
the both are defined the driver attempts to set referenced clock to the
|
|
defined rate and takes the rate from the clock reference.
|
|
|
|
Board connectors:
|
|
|
|
* Headphone Jack
|
|
* Line Out
|
|
* Mic Jack
|
|
* Line In
|
|
|
|

|
|

ti,mcasp-controller = <&mcasp1>;
