|
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.
