SC7180, SM6350 and SM6375 use a rather similar hw setup for DPU, with the main exception being that the last one requires an additional throttle clock. It is not well understood yet, but failing to toggle it on makes the display hardware stall and not output any frames. Document SM6350 and SM6375 DPU.
