If we can assume all boards have static configuration on each PSC and we don't have to switch protocols at runtime, we can put info how each PSC is configured on the hardware via device properties in board specific init functions, and au*_match function can check the values. Or, if we can assume the firmware configures each PSC properly, we can read current settings from the PSC register in match function. --- Izumi Tsutsui
