+Subject: Revert "drm/amd/display: edp do not add non-edid timings"
+
+From: Hersen Wu <hersenxs.wu@amd.com>
+
+commit d6149086b45e150c170beaa4546495fd1880724c upstream.
+
+This change causes regression when eDP and external display in mirror
+mode. When external display supports low resolution than eDP, use eDP
+timing to driver external display may cause corruption on external
+display.
+
+This reverts commit e749dd10e5f292061ad63d2b030194bf7d7d452c.
