13*4882a593Smuzhiyun  The audio clock controller generates and supplies the clocks to the audio
14*4882a593Smuzhiyun  codec.
15*4882a593Smuzhiyun
16*4882a593Smuzhiyun  Each clock is assigned an identifier and client nodes use this identifier
17*4882a593Smuzhiyun  to specify the clock which they consume.
18*4882a593Smuzhiyun
19*4882a593Smuzhiyun  All these identifiers could be found in
20*4882a593Smuzhiyun  <dt-bindings/clock/marvell,mmp2-audio.h>.
