Hi Vladimir, as we are preparing to submit the code for multi-power
domain support for the clock controller in our series
(https://lore.kernel.org/all/20250306-videocc-pll-multi-pd-voting-v2-0-0cd00612bc0e@quicinc.com),
there has been a request to incorporate the CAMCC-related changes as
well. If you are okay with us including this series changes(maintaining
your authorship) in our series, then we can integrate them and address
any comments in our next submission.
