Looks like we've since gained support for packed YUV formats, so this
patch needs a respin to include those as well.

A while ago Daniel mentioned he can resolve minor/small 
merge conflicts and don't have to respun. 
So my understanding is this should be ok as it should be 
minor one.

Something like this may not even show up as a conflict since you're just
adding a new table. And even if it does, it would be very easy to
overlook the fact that the new table should also have the 4:2:2 formats.

Ok, will respun this patch with YUV packed formats patch being applied.

Minor conflicts = changes around the code you're changing that doesn't
materially affect your patch.

This here seems like a full-blown feature conflict and means we might even
need to retest (and also make sure test coverage is still adequate).

Agree, patch has been rebased and updated patch resubmitted after retesting.
