13description:
14  The CPRMAN clock controller generates clocks in the audio power domain of the
15  BCM2835.  There is a level of PLLs deriving from an external oscillator, a
16  level of PLL dividers that produce channels off of the few PLLs, and a level
17  of mostly-generic clock generators sourcing from the PLL channels.  Most other
18  hardware components source from the clock generators, but a few (like the ARM
19  or HDMI) will source from the PLL dividers directly.
