The fact that some DSA device trees use 'label = "cpu"' for the CPU port is nothing but blind cargo cult copying. The 'label' property was never part of the DSA DT bindings for anything except the user ports, where it provided a hint as to what name the created netdevs should use. DSA does use the "cpu" port label to identify a CPU port in dsa_port_parse(), but this is only for non-OF code paths (platform data). The proper way to identify a CPU port is to look at whether the 'ethernet' phandle is present.
