Are these (especially the clock and polarity) things that are going to vary at runtime? I'd have expected these to come from the hardware rather than being something that could usefully change.
Some microphone support low power modes that use a slower clock. Polarity will probably not change at run-time, but clock speed can change to move mics from low power/low-resolution to higher power/high-resolution mode.
So polarity can be made hardware specific but clocks should be configurable.
I can break these out into separate patches if you want.
Please, and make the bits that can't usefully vary DT properties.
