Subject: [PATCH/RFC 05/15] dt-bindings: display: bridge: thc63lvd1024: Document dual-link operation
Date: Thu,  7 Mar 2019 01:23:35 +0200	[thread overview]
Message-ID: <20190306232345.23052-6-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190306232345.23052-1-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.

+The device can operate in single-link mode or dual-link mode. In single-link
+mode, all pixels are received on port@0, and port@1 shall not contain any
+endpoint. In dual-link mode, even-numbered pixels are received on port@0 and
+odd-numbered pixels on port@1, and both port@0 and port@1 shall contain
