Subject: [PATCH V5 1/2] dt-bindings: display: bridge: lvds-codec: Document pixel data sampling edge select

From: Marek Vasut <[email-masked]>
Date: Wed, 2 Jun 2021 22:36:07 +0200

The OnSemi FIN3385 Parallel-to-LVDS encoder has a dedicated input line to
select input pixel data sampling edge. Add DT property "pclk-sample", not
the same as the one used by display timings but rather the same as used by
media, to define the pixel data sampling edge.
