From 629212c5f7b2c2c889396a7eded3d86522988d93 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Fri, 28 Jul 2023 18:10:53 +0100 Subject: [PATCH] drm/panel: waveshare: Fix up timings for 10.1" panel The 10.1" panel doesn't work with the timings defined. vc4 will always have been fixing up the timing due to the limited integer divider, so compute the fixed up mode and use it directly.
