title: Marvell MMP2 Audio Clock Controller

description: |

  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>.
