This almost pleads to go to a separate patch. Fixes generally should
be separated from the rest of the changes.


Thanks Dmitry for your review.

Sure, will separate this into a separate patch in next series.

Are these values applicable to sm8450?


No, the shift clocks above are part of SM8650 only. To reuse the existing SM8550 videocc driver for SM8650 and to register these shift clocks for SM8650, I added them here.

Thanks,
Jagadeesh
