|
The audio clock controller generates and supplies the clocks to the audio
|
||
|
|
codec.
|
||
|
|
|
||
|
|
Each clock is assigned an identifier and client nodes use this identifier
|
||
|
|
to specify the clock which they consume.
|
||
|
|
|
||
|
|
All these identifiers could be found in
|
||
|
|
<dt-bindings/clock/marvell,mmp2-audio.h>.
