[PATCH 1/2] drm/docs: Record TODO about plane clipping

[Daniel Vetter]

It's such a mess that it's become a FAQ :(

+Clean up the clipped coordination confusion around planes
+---------------------------------------------------------

+We have a helper to get this right with drm_plane_helper_check_update(), but
+it's not consistently used. This should be fixed, preferrably in the atomic
+helpers (and drivers then moved over to clipped coordinates). Probably the
+helper should also be moved from drm_plane_helper.c to the atomic helpers, to
+avoid confusion - the other helpers in that file are all deprecated legacy
+helpers.

+Implement deferred fbdev setup in the helper
+--------------------------------------------
+
+Many (especially embedded drivers) want to delay fbdev setup until there's a

+fbdev default. Many drivers have a hacked-up (and often broken) version of this,

Yeah, there also seems to have been a slew of new drivers adding their
custom implementations recently. I think I have a version of the series
that's based on something more recent that I've been meaning to send
out, but kept getting side-tracked.
