as you were working on the rk3128-inno-hdmi variant recently
and I don't really have a rk3036 or rk3128 in working condition
right now, could you give this series a try.
For reference, the full series is at lore:
https://lore.kernel.org/dri-devel/20240521105817.3301-1-keith.zhao@starfivetech.com/
and generalizes the inno-hdmi driver into the bridge model we
have in a number of other places already.
Thanks
