Nice.

I compared this to WIP for x1e80100 which looks nearly register 
compatible. Use of the shared_ops indicates to me you've thought about 
which clocks should not be switched all the way off.

That said .. please fix the name here "cam_cc-sm8650". The title of your 
series is "camcc-sm8650" which IMO is a much more appropriate name.

The admixture of hyphen "-" and underscore "_" is some kind of 
tokenisation sin.
