Subject: [PATCH v5 2/3] ARM: dts: r8a7791: Convert to new LVDS DT bindings
Date: Fri,  6 Apr 2018 22:14:37 +0300	[thread overview]
Message-ID: <20180406191438.3630-3-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20180406191438.3630-1-laurent.pinchart+renesas@ideasonboard.com>

The internal LVDS encoder now has DT bindings separate from the DU. Port
the device tree over to the new model.

Fixes: c6a27fa41fab ("drm: rcar-du: Convert LVDS encoder code to bridge driver")
Fixes: bb21803ea440 ("ARM: dts: r8a7791: add soc node")
Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
---
Changes since v3:

- Added power-domains and resets properties to LVDS nodes

Changes since v2:

- Fixed LVDS compatible string

Changes since v1:

- Remove the DU reg-names property
