Subject: [PATCH 1047/1795] dt-bindings: display: renesas: Deprecate LVDS
support in the DU bindings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The internal LVDS encoders now have their own DT bindings, representing
them as part of the DU is deprecated.
