And I think the result is very clean. Great work!

I have tested it in X86 and in arm64, with similar performance as the
previous patchset.

Maybe you want to cherry pick that commit into your series I can also
send the patch to the list for review if you prefer so.

At least in 5.11 rc5 I the same dmadev worked in arm64 and x86.

Given that Sergey mentioned the v4l patchset needs more work I'll
use your commit as the example for sending out my series.

Thanks for all the work!
