Did you mean is instead of = ? Are you missing "and" somewhere in this sentence

No action needed, just a question. Can we output tiled out of the PP ? If so,
perhaps we could handle the alignment difference by enabling the PP even if
tiled. That would greatly help to handle compatibility between decoders and
encoders in the future.

I remember seeing limits to 4096 instead in VSI documentation (UWHD). Just like
many hardcoded limits in this driver, perhaps the limits was copied from the
white paper performance example. It would be weird that we can decode portrait
UHD/FHD.
I think for this patch, what I'd like to see is the UDH and FHD limits to be set
as a define. Since if we got them wrong, fixing them later after this patch
becomes a lot more work, as its copied over and over.
Everything else looks good to me know, thanks for the update.
