* input rail.
* None of them seem to make any sense in relation to detecting USB devices
* or whether there is power provided via any USB pins: they would always
* report high, otherwise the system wouldn't be running.
* The AXP717C provides proper USB-C CC pin functionality, but the PMIC is
* not connected to those pins of the USB-C connector.
