title: Marvell MMP2 Audio Clock Controller

maintainers:
  - Lubomir Rintel <lkundrak@v3.sk>

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>.
