I looked at the new PRCM description, which is very detailed.
I have some questions though:

1. There is a "PLL_AUDIO control". Is this a new PLL? Or just another
set of mapped
   registers for PLL_AUDIO in CCU? I assume it is the latter.

2. What is the source of "24 MHz" in the main CCU? The external 24 MHz
oscillator
   (HOSC) or the mux after HOSC and CLK16M_RC? (ref: page 331, the
PRCM block diagram)

Please help clarify them. Thank you.
