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.
