Subject: [PATCH v7 4/6] dt-bindings: display: hdmi-connector: Support DDC bus enable
Date: Thu, 20 Jun 2019 15:47:46 +0200 [thread overview]
Message-ID: <20190620134748.17866-5-megous@megous.com> (raw)
In-Reply-To: <20190620134748.17866-1-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.
