From 2befa6407d5c8b543be32c2276d396db395d9d02 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 15 Jan 2026 03:39:42 +0100 Subject: [PATCH] dt-bindings: display: bridge: waveshare,dsi2dpi: Document 1..4 DSI lane support Describe 1..4 DSI lanes as supported. Internally, this bridge is an ChipOne ICN6211 which loads its register configuration from a dedicated storage and its I2C does not seem to be accessible. The ICN6211 supports up to 4 DSI lanes, so this is a hard limit for this bridge. The lane configuration is preconfigured in the bridge for each of the WaveShare panels.
