      drm/atomic: add plane iterator macros · dd275956
      Rob Clark authored
      Add helper macros to iterate the current, or incoming set of planes
      attached to a crtc.  These helpers are only available for drivers
      converted to use atomic-helpers.

      [danvet: Squash in fixup from Rob to move the planemask iterator to
      drm_crtc.h and document it. That one is needed by the atomic ioctl so
      can't be in a helper library.]

      drm/atomic: track bitmask of planes attached to crtc · 6ddd388a
      Rob Clark authored
      Chasing plane->state->crtc of planes that are *not* part of the same
      atomic update is racy, making it incredibly awkward (or impossible) to
      do something simple like iterate over all planes and figure out which
      ones are attached to a crtc.
      
      Solve this by adding a bitmask of currently attached planes in the
      crtc-state.
      
      Note that the transitional helpers do not maintain the plane_mask.  But
      they only support the legacy ioctls, which have sufficient brute-force
      locking around plane updates that they can continue to loop over all
      planes to see what is attached to a crtc the old way.

      [danvet:
      - Drop comments about locking in set_crtc_for_plane since they're a
        bit misleading - we already should hold lock for the current crtc.
      - Also WARN_ON if get_state on the old crtc fails since that should
        have been done already.
      - Squash in fixup to check get_plane_state return value, reported by
        Dan Carpenter and acked by Rob Clark.]
