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