[PATCH V3 1/2] dt-bindings: display: bridge: lvds-codec: Document LVDS data mapping select

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
