Subject: [PATCH v4 02/16] dt-bindings: display: renesas: Deprecate LVDS support in the DU bindings
Date: Wed, 21 Feb 2018 01:10:32 +0200	[thread overview]
Message-ID: <20180220231046.32638-3-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20180220231046.32638-1-laurent.pinchart+renesas@ideasonboard.com>

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

Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
Reviewed-by: Rob Herring <robh@kernel.org>

Changes since v1:

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