Subject[PATCH/RFC 02/12] dt-bindings: display: renesas: lvds: Document renesas,swap-data
R-Car D3, R-Car E3, and RZ/G2E support dual-link mode.
In such a mode, the first LVDS encoder emits even data, and the
second LVDS encoder emits odd data. This patch documents property
renesas,swap-data, used to swap even and odd data around.
