| H A D | link_dpms.c | a6c0c9f5 Thu Mar 30 03:38:59 CDT 2023 Jingwen Zhu <Jingwen.Zhu@amd.com> drm/amd/display: Improvement for handling edp link training fails
[Why]
The eDP retrain will cause the DPCD 300 to be reset to default.
And cause the brightness can't be set correctly.
[How]
delete the call to edp panel power control in both
enable_link_output/disable_link_output entirely and
only call edp panel control in enable_link_dp and
disable_link_dp once.
