drm/i915/display: Detect AuxCCS support via display parent interfaceWhether AuxCCS can be properly supported depends on the support both fromthe display side and non-display side of the driver.Let us therefore allow for the non-display part to be queried via thedisplay parent interface.The new interface replaces the HAS_AUX_CCS macro and we also remove theFIXME from skl_universal_plane_create since now the xe will not advertisethe AuxCCS caps to start with so they do not need to be removed afterenumeration.Also, by removing this build specific FIXME we come a step closer to fullyde-coupling display and non-display.The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is stillrequired for determining the need for PLANE_AUX_DIST programming.Signed-off-by: Tvrtko Ursulin References: cf48bddd31de ("drm/i915/display: Disable AuxCCS framebuffers if built for Xe")Cc: intel-gfx@lists.freedesktop.orgCc: intel-xe@lists.freedesktop.orgCc: Jani Nikula Cc: José Roberto de Souza Cc: Juha-Pekka Heikkila Cc: Rodrigo Vivi Cc: Ville Syrjälä Acked-by: Jani Nikula # v1Reviewed-by: Jani Nikula Signed-off-by: Tvrtko Ursulin Link: https://lore.kernel.org/r/20251209120034.9143-1-tursulin@igalia.com List of files: /linux/include/drm/intel/display_parent_interface.h
