Subject: [PATCH v3 06/11] dt-bindings: display: hdmi-connector: Add DDC power supply

From: Ondrej Jirman <megous@...ous.com>

Some Allwinner SoC using boards (Orange Pi 3 for example) need to enable
on-board voltage shifting logic for the DDC bus to be usable. Use
ddc-supply on the hdmi-connector to model this.

Add binding documentation for optional ddc-supply property.
