Subject: drm/panel: simple: Update timings for AUO G101EVN010
X-Git-Tag: v6.16-rc1~33^2~20^2~9

drm/panel: simple: Update timings for AUO G101EVN010

Switch to panel timings based on datasheet for the AUO G101EVN01.0
LVDS panel. Default timings were tested on the panel.

Previous mode-based timings resulted in horizontal display shift.
