PD_N is not a power supply input, so modelling it as a regulator makes no sense: "If PD_N is LOW, then the device is in Deep power-down completely, even if supply rail is ON; for the device to be able to operate, the PD_N pin must be HIGH." -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
