81af63a4af drm: Don't pass clip to drm_atomic_helper_check_plane_state() 
Move the plane clip rectangle handling into
drm_atomic_helper_check_plane_state(). Drivers no longer
have to worry about such mundane details.

v2: Convert armada, rcar, and sun4i as well
v3: Resolve simple_kms_helper conflict

bd6120dbcb drm/mediatek: Use drm_mode_get_hv_timing() to populate plane clip rectangle 
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

No functional changes as the code already uses crtc_state->mode
to populate the clip, which is also what drm_mode_get_hv_timing()
uses.

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

10b47ee02d drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state() 
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.

We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

e6fc3b6855 drm: Plumb modifiers through plane init 
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

0e4faf679e drm/mediatek: Use drm_plane_helper_check_state() 
Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.

This also eliminates the double clipping the driver was doing
in both check and commit phases). And it should fix src coordinate
addr adjustement. Previously the driver was expecting negative dst
coordinates after clipping, which is not going happen, so any clipping
induced addr adjustment simply didn't happen. Neither did the driver
respect any user configured src coordinates, so panning and such would
have been totally broken. It should be all good now.

9b8b013dde drm: Deal with rotation in drm_plane_helper_check_update() 
drm_plane_helper_check_update() needs to account for the plane rotation

helper instead. An updated patch never materialized AFAICS, so I went
ahead and cooked one up myself.
