Mon, 02 Oct 2023 03:21:10 -0700 (PDT) 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.
