Subject: [PATCH v3 02/10] dt-bindings: display: bridge: thc63lvd1024: Document dual-link operation
Date: Tue, 28 May 2019 17:12:26 +0300 [thread overview]
Message-ID: <20190528141234.15425-3-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190528141234.15425-1-laurent.pinchart+renesas@ideasonboard.com>
The THC63LVD1024 LVDS decoder can operate in two modes, single-link or
dual-link. In dual-link mode both input ports are used to carry even-
and odd-numbered pixels separately. Document this in the DT bindings,
along with the related rules governing port and usage.
