This patch adds active plane reconfiguration support for imx-drm.
This may fixes some mode setting failure issues which were introduced
by imx-drm atomic conversion patch set. The main idea is to disable the
plane in question in CRTC's atomic_disable operation and then the drm
atomic core will enable it again automatically.
v3->v4:
* Change the bool active_only parameter of commit_planes() to an uint32_t
parameter named 'flags' and add two flags - DRM_PLANE_COMMIT_ACTIVE_ONLY
and DRM_PLANE_COMMIT_NO_DISABLE_AFTER_MODESET. This way, the drm atomic
core is able to skip the atomic_disable call for the planes which are
committed with the NO_DISABLE_AFTER_MODESET flag set.
* Fix the helper disable_planes_on_crtc(), which is needed for CRTC's
atomic_disable callback to disable planes.
* Improve kernel-doc of CRTC's atomic_disable callback to address Daniel
Vetter's comment.
* Do not wait for DMFC FIFO to clear to avoid timeout warning, as the
precedure to disable display channel is changed slightly after the
NO_DISABLE_AFTER_MODESET flag is used.
v2->v3:
* Disable all appropriate affected planes(when necessary) in CRTC's
->atomic_disable callback, but not in each plane's ->atomic_update callback,
as suggested by Daniel Vetter.
* +Cc Lucas Stach, as he tested the patch v2.
v1->v2:
* Do not reject reconfiguring an active overlay plane.
