Without enabling it, these pipes remain inaccessible. The DPU is supplied by both CORE and INT2, so describe both GDSCs as its power domains rather than attaching the DPU directly to their parent MMCX domain. Keep CORE attached to the parent MDSS device because it also supplies shared MDSS hardware outside the DPU.
