Subject: [PATCH 1/3] dt-bindings: display: hdmi-connector: add hdmi-pwr supply
Date: Sun, 7 May 2023 23:12:16 +0300 [thread overview]
Message-ID: <20230507201218.2339014-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230507201218.2339014-1-dmitry.baryshkov@linaro.org>
Follow the dp-connector example and add hdmi-pwr supply to drive the 5V
pin of the HDMI connector (together with some simple glue logic possibly
attached to the connector).
