drm: convert crtc and connection_mutex to ww_mutex (v5)
For atomic, it will be quite necessary to not need to care so much about locking order. And 'state' gives us a convenient place to stash a ww_ctx for any sort of update that needs to grab multiple crtc locks. Because we will want to eventually make locking even more fine grained (giving locks to planes, connectors, etc), split out drm_modeset_lock and drm_modeset_acquire_ctx to track acquired locks. Atomic will use this to keep track of which locks have been acquired in a transaction. v1: original v2: remove a few things not needed until atomic, for now v3: update for v3 of connection_mutex patch.. v4: squash in docbook v5: doc tweaks/fixes Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
