[PATCH v2 1/4] dt-bindings: soc: qcom: qcom,pmic-glink: add a gpio used to determine the Type-C port plug orientation

[Neil Armstrong]

On SM8450 and SM8550 based platforms, the Type-C plug orientation is given on a
GPIO line for each connector which are set by the PMIC(s).

Document this optional Type-C connector property, and take the
assumption an active level represents an inverted/flipped orientation.
