Hi all,

I am submitting a common clock driver for Numerically Controlled Oscillator (NCO)
blocks on recent Apple ARM64 SoCs. The NCO driver will be used for audio
support on these platforms which is work-in-progress.

I suppose the only noteworthy thing is the blocks divide an input clock
with a clock cycle counter in part implemented as a LFSR. For that reason
the driver upfront calculates a table of LFSR states to be able to program
the dividers.

Best,
Martin
