The DT parts should have been posted in the same series then, so as to
not cause breakage after the series is applied, and to preserve bisect
as much as possible.

IMHO, the whole series needs to be merged together even if parts of it
come from individual maintainers as immutable commits.

Do the DT portions cause merge conflicts with what is already there in

I think the next step would be to post the series again, this time with
DT changes included. Whether it goes into v5.9 or v5.10, thats probably
needed anyway.
