0012 description: |
0013   The audio clock controller generates and supplies the clocks to the audio
0014   codec.
0015
0016   Each clock is assigned an identifier and client nodes use this identifier
0017   to specify the clock which they consume.
0018
0019   All these identifiers could be found in
0020   <dt-bindings/clock/marvell,mmp2-audio.h>.
