drm/msm: update cursors asynchronously through atomic
Add support to async updates of cursors by using the new atomic interface for that. Basically what this commit does is do what mdp5_update_cursor_plane_legacy() did but through atomic. v5: call drm_atomic_helper_async_check() from the check hook v4: add missing atomic async commit call to msm_atomic_commit(Archit Taneja) v3: move size checks back to drivers (Ville Syrjälä) v2: move fb setting to core and use new state (Eric Anholt) Cc: Rob Clark <robdclark@gmail.com> Cc: Archit Taneja <architt@codeaurora.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.com> Tested-by: Archit Taneja <architt@codeaurora.org> (v4) [added comment about not hitting async update path if hwpipes are re-assigned or global state is touched] Signed-off-by: Rob Clark <robdclark@gmail.com>
