Subject: [PATCH v6 5/5] drm/panel-edp: Fix AUO 0x405c panel naming and add a variant
Date: Thu,  7 Mar 2024 14:57:45 -0800

There are 2 different AUO panels using the same panel id. One of the
variants requires using overridden modes to resolve glitching issue as
described in commit 70e0d5550f5c ("drm/panel-edp: Add auo_b116xa3_mode").
Other variants should use the modes parsed from EDID.
