The other architectures have not a so complex mechanism as Allwinner's.
The 'divider'/'fractional-divider'/multiplier'/... "standard" functions
cannot be used in ou case. Your 'sunxi-ng' just add new structures to
replace them, and, in fact, you are building an other restricted
composite clock system. which will be unusable when new SoCs will
appear.

Yes, I should not have include the reset/bus gate/factor computation
stuff in my patch series. Because the only important part is to have a
flat definition of all the parameters giving this more simplification:
one structure and one source file.
