I do believe this part, as well as setting the default .write_mask = false
for the existing parts should get its own patch + a bit more explanation
on what this does and why it's needed.
---- 8< ----
drm/rockchip: Add support for interrupt registers using write-masks
Some new display-controllers are need to set write-masks to enable writes
to interrupt registers. Allow this to be set on a per-vop basis.
---- 8< ----
or something like that, and then patches 2+3 being the rk3229 support +
binding.

I'm not sure we need that extra "DUMMY_INTR" define - a simple 0 should be
enough as well to mark the positions as unused.
The rest looks nice
