Our commit functions today include sleepable work, so those operations need to be split out and run either before or after the atomic register programming. The solution here calculates which of those operations will need to be performed during the 'check' phase and sets flags in an intel_crtc sub-struct. New intel_begin_crtc_commit() and intel_finish_crtc_commit() functions are added before and after the actual register programming; these will eventually be called from the atomic plane helper's .atomic_begin() and .atomic_end() entrypoints. v2: Fix broken sprite code split v3: Make the pre/post commit work crtc-based to match how we eventually want this to be called from the atomic plane helpers. v4: Some platforms that haven't had their watermark code reworked were waiting for vblank, then calling update_sprite_watermarks in their platform-specific disable code. These also need to be flagged out of the critical section. v5: Sprite plane test for primary show/hide should just set the flag to wait for pending flips, not actually perform the wait. (Ander) v6: - Rebase onto latest di-nightly; picks up an important runtime PM fix. - Handle 'wait_for_flips' flag in intel_begin_crtc_commit(). (Ander) - Use wait_for_flips flag for primary plane update rather than performing the wait in the check routine. - Added kerneldoc to pre_disable/post_enable functions that are no longer static. (Ander) - Replace assert_pipe_enabled() in intel_disable_primary_hw_plane() with an intel_crtc->active test; it turns out assert_pipe_enabled() grabs some mutexes and can sleep, which we can't do with interrupts disabled.
