It is entirely possible that there will never be USB power supply connected to a particular board. There is also the possibility of using just the ACIN part, for which I will be submitting a driver soon (courtesy of Bruno Prémont). On the other hand, the USB supply is probably so common that we could just enable it. A board may choose to disable it or simply ignore the issue. After all, the driver will correctly report on POWER_SUPPLY_PROP_PRESENT and POWER_SUPPLY_PROP_ONLINE.
