Subject: [PATCH/RFC 02/12] dt-bindings: display: renesas: lvds: Document renesas,swap-data
Date: Fri, 2 Aug 2019 08:33:59 +0100 [thread overview]
Message-ID: <1564731249-22671-3-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1564731249-22671-1-git-send-email-fabrizio.castro@bp.renesas.com>
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.
