    +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.h>.
