[PATCH V2 1/2] dt-bindings: display: bridge: lvds-codec: Document LVDS data mapping select

Marek Vasut marex at denx.de
Wed Jun 2 20:37:30 UTC 2021


Decoder input LVDS format is a property of the decoder chip or even
its strapping. Add DT property data-mapping the same way lvds-panel
does, to define the LVDS data mapping.
