Subject: [PATCH v2 02/12] dt-bindings: display: renesas: Deprecate LVDS support in the DU bindings
Date: Sat, 13 Jan 2018 01:14:20 +0200	[thread overview]
Message-ID: <20180112231430.26943-3-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20180112231430.26943-1-laurent.pinchart+renesas-ryLnwIuWjnjg/C1BVhZhaw@public.gmane.org>

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-ryLnwIuWjnjg/C1BVhZhaw@public.gmane.org>
---
Changes since v1:

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