This helper function makes sure that damage from plane state is discarded for full modeset cycle. For some reason, which makes damage irrelevant, driver might want to do a full plane update for e.g. full modeset. Such cases must be checked here.

Note: In the previous version of the patch the name was clear damage. IMO the new name check_plane_damage() make more sense as this function really will be validating if need to discard damage.

From: Rob Clark robdclark@gmail.com

Add an atomic helper to implement dirtyfb support. This is needed to support DSI command-mode panels with x11 userspace (ie. when we can't rely on pageflips to trigger a flush to the panel).

v2: Modified the helper to use plane fb_damage_clips property and removed plane_state::dirty flag.

v3: - Use uapi drm_mode_rect. - Support annotate flags.

Add a new struct vmw_du_update_plane similar to vmw_kms_dirty which represent the flow of operations needed to update a display unit from surface or bo (blit a new framebuffer).

v2: - Kernel doc correction. - Rebase.
