[Intel-gfx] [PATCH -v4 0/4] split plane's updates functions into check() and commit()

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

This is the beginning of the work to prepare i915 for the upcoming
atomic modesetting API. Here we split the plane update fucntions in
the check and commit states.

v2: use struct intel_plane_state to keep states between check and
commit stages.

v3: take Ville's comments:
        - rename pstate to state
        - get rid of non-drm_rect coordinates in intel_plane_state
        - keep 'clip' const

v4: take more Ville's comments:
	- populates orig_dst and orig_src too
	- use orig_dst coordinates to program the cursor plane

Gustavo Padovan (4):
  drm/i915: create struct intel_plane_state
  drm/i915: split intel_update_plane into check() and commit()
  drm/i915: split intel_cursor_plane_update() into check() and commit()
  drm/i915: split intel_primary_plane_setplane() into check() and
    commit()
