From 3cb120814eb956d3673e00a419cb6cc6a82c15fe Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 4 Mar 2019 21:47:51 +0200 Subject: [PATCH] dt-bindings: display: bridge: thc63lvd1024: Document dual-link operation 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.
