I mean, unlike usb-b-connector (where ID and Vbus can be simple GPIOs nearly directly connected to the pins of the connector) for the USB-C the orientation is not a connector's GPIO, but rather some additional not elementary logic. > + > # The following are optional properties for "usb-c-connector" with power > # delivery support. > source-pdos: >

On some platforms, the Type-C plug orientation is given on a GPIO line. Document this optional Type-C connector property, and take the assumption an active level represents an inverted/flipped orientation.
