Thank you for the patch. Please see my comments inline.

What does this "..." mean?

nit: In principle the clocks should be named after the function the clock
performs on the consumer side, i.e. the JPEG block in this case, I guess
here it's just a generic clock that does everything, but I guess it comes
from somewhere. Is it the AHB clock or something? In that case it would
normally be called "ahb".

I believe this isn't necessary anymore, because larbs are added
automatically by the MTK IOMMU driver using device links. +CC Yong who
worked on that.

Ditto.
