Subject: [PATCH v6 4/6] dt-bindings: display: hdmi-connector: Support DDC bus enable
Date: Mon, 27 May 2019 18:22:35 +0200 [thread overview]
Message-ID: <20190527162237.18495-5-megous@megous.com> (raw)
In-Reply-To: <20190527162237.18495-1-megous@megous.com>
From: Ondrej Jirman <megous@megous.com>
Some Allwinner SoC using boards (Orange Pi 3 for example) need to enable
on-board voltage shifting logic for the DDC bus using a gpio to be able
to access DDC bus. Use ddc-en-gpios property on the hdmi-connector to
model this.
Add binding documentation for optional ddc-en-gpios property.
