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.
