[PATCH v3 02/12] dt-bindings: display: renesas: Deprecate LVDS support in the DU bindings

From: Laurent Pinchart <hidden>
Date: 2018-02-15 00:04:05
Also in: dri-devel, linux-renesas-soc
Subsystem: drm drivers, drm drivers and misc gpu patches, open firmware and flattened device tree bindings, the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

The internal LVDS encoders now have their own DT bindings, representing
them as part of the DU is deprecated.

Changes since v1:

- Remove the LVDS reg range from the example
- Remove the reg-names property
