+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.
