Hi,
This is the v3 patch set to convert imx drm into atomic mode setting. It takes 3 phases to achieve the goal.
v2->v3: * Rebase onto Daniel Vetter's open git branch topic/drm-misc so that we may better support nonblock atomic commit with the aid from drm atomic helper. * Remove dw-hdmi bridge driver's legacy drm_connector_funcs struture step-by-step instead of doing that in patch 04/10 directly. So, patch 08/10 in this set is newly introduced.
v1->v2: * Rebase onto Philipp Zabel's open git branch imx-drm/next as Philipp required. * Drop patch 05/14 and 10/14 in v1 which touch drm core to disable plane in transitional helper drm_helper_crtc_mode_set and in drm_atomic_helper_disable_all, because we won't get ipu plane resource in v2 when updating plane and failure won't happen. * Wait for pending commit on each CRTC for both block and nonblock atomic mode settings. This way, a block commit will not overwrite the hardware setting when a nonblock page flip is about to finish, so that the page flip may wait for vblank successfully. * See changelogs in each patch for other trivial updates.
