Subject: [PATCH 2/4] dt-bindings: panel: lvds: Add properties for clock and data polarities
Date: Fri, 14 Feb 2020 13:24:39 +0100 [thread overview]
Message-ID: <620a740cec4186177ce346b092d4ba451e1420dc.1581682983.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.b12a054012ce067fa2094894147f953ab816d8d0.1581682983.git-series.maxime@cerno.tech>
Some LVDS encoders can support multiple polarities on the data and
clock lanes, and similarly some panels require a given polarity on
their inputs. Add a property on the panel to configure the encoder
properly.
