There are no clocks that are configurable from the PowerPC side
(well, maybe things like the USB clocks, but we do not know how).

0c000000 is the flipper-compatible stuff
0d000000 is the hollywood new devices
0d800000 is the same as part of 0d000000, but with some extra bits
sometimes.

It's SPI I think, with some extra signals.  It's the gamepads mostly.
