However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for acks received on the version they apply.

[PATCH v6 4/6] dt-bindings: display: hdmi-connector: Support DDC bus enable
From: Ondrej Jirman 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.
