[PATCH v2 1/8] dt-bindings: connector: usb-connector: add a gpio used to determine the Type-C port plug orientation

[Neil Armstrong <neil.armstrong@linaro.org>]

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.
