From: Tvrtko Ursulin <[email protected]> Whether AuxCCS can be properly supported depends on the support both from the display side and non-display side of the driver.
Let us therefore allow for the non-display part to be queried via the display parent interface. The new interface replaces the HAS_AUX_CCS macro and we also remove the FIXME from skl_universal_plane_create since now the xe will not advertise the AuxCCS caps to start with so they do not need to be removed after enumeration. Also, by removing this build specific FIXME we come a step closer to fully de-coupling display and non-display. The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is still required for determining the need for PLANE_AUX_DIST programming.
