From 02ce5b14d69bf513f3c6cc93c005cae07db985a0 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Fri, 26 Mar 2021 17:06:36 +0000 Subject: [PATCH] drm/panel-simple: Add a timing for the Raspberry Pi 7" panel The Raspberry Pi 7" 800x480 panel uses a Toshiba TC358762 DSI to DPI bridge chip, so there is a requirement for the timings to be specified for the end panel. Add such a definition.
