Subject: [PATCH RFC 1/7] dt-bindings: connector: usb-connector: add a gpio used to determine the Type-C port plug orientation
Date: Thu, 01 Jun 2023 16:07:01 +0200 [thread overview]
Message-ID: <20230601-topic-sm8550-upstream-type-c-v1-1-d4d97b4d8bab@linaro.org> (raw)
In-Reply-To: <20230601-topic-sm8550-upstream-type-c-v1-0-d4d97b4d8bab@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.
