This series adds the new DT node, but there are no board DTs in upstream
that will use VIP? Will we see the board patches?

In any case, given that you're likely the only one here who has access
to hardware with VIP, you should promote yourself to the tegra-video
driver maintainers and confirm that you will be able to maintain and
test this code for years to come.
