drm/i915: Introduce crtc_state->update_planes bitmask
Keep track which planes need updating during the commit. For now we set the bit for any plane that was or will be visible (including icl+ nv12 slave planes). In the future I'll have need to update invisible planes as well, for skl plane ddbs and for pre-skl pipe gamma/csc control (which lives in the primary plane control register). v2: Pimp the commit message to mention icl+ nv12 slave planes (Matt) Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181127163742.30215-1-ville.syrjala@linux.intel.com
