To add to that, a few things I've noticed (but I've mostly only gotten
as far as the front-end of the pipeline, ie. dpu_plane):

 - It looks like, as was the case with mdp4/mdp5 (and really most other hw)
   there are still unequal capabilities for planes (ie. some can do YUV,
   scaling, etc).

   But drm-hwc (or weston) isn't going to know about that, so I think we'll
   need to add support for dynamically assigning dpu_plane::pipe, similar
   to what mdp5 does w/ plane<->hwpipe.  (Which I actually added specifically
   for drm-hwc ;-))

 - I *think* we also need the same trick for combining mixers under one CRTC
   for 4k modes too?

 - in dpu_plane, and perhaps elsewhere, userspace pointers for things like CSC
   and scaling coefficients need to be annotated w/ __user.  (Except the should
   probably be blob properties instead.. and we probably need to strip out the
   custom properties and re-introduce them separately with some userspace +
   review.)

 - dpu_formats.c looks mostly like a superset of mdp_format.c, ie there is a
   similar concept to how you describe the format to hw as mdp4/mdp5.  Probably
   the additions in dpu_formats should be folded back in mdp_format.

I'm not sure how we want to balance adding new features with cleanup
and hopefully removing some code.  I suspect a fair chunk of dpu_plane
actually belongs in dpu_plane_state, so maybe we can handle that as
part of that cleanup.

Some of these changes in drm core need to be split out.
