[PATCH 5/4] dt-bindings: display: bridge: thc63lvd1024: Document dual-output mode

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
Date: 2020-05-13 23:21:39
Also in: dri-devel, linux-renesas-soc
Subsystem: drm drivers, drm drivers and misc gpu patches, drm drivers for bridge chips, open firmware and flattened device tree bindings, the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Andrzej Hajda, Neil Armstrong, Robert Foss, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

The DT binding support both dual-input and dual-output mode, but only
dual-input is documented. Document dual-output mode.
