12description: |
13  The audio clock controller generates and supplies the clocks to the audio
14  codec.
15
16  Each clock is assigned an identifier and client nodes use this identifier
17  to specify the clock which they consume.
18
19  All these identifiers could be found in
20  <dt-bindings/clock/marvell,mmp2-audio.h>.
