bool "Charge-Through VCONN-Powered Device"
help
This enables support for supplying power to devices, with a circuit
that deals with this without needing the involvement of the main
device.

bool "Dual-Role Port, Audio Accessory, and Try.SRC Device"
help
This is the most flexible option, allowing the port to operate in
a dual-role capacity, so that power can be accepted or supplied on
a port.
