No need to reorder these ports. Please add DP to the end.

This will not validate against the schema. Please add p1 region at the 
end (I assume it is <0 0x0ae91400 0 0x400>).

Right, but I'll keep the dpu_intf0_out label for this port,
but having dpu_intf1_out, dpu_intf2_out then dpu_intf0_out isn't very clean...
