[PATCH v4] Revert "drm/amd/display: Expose connector VRR range via debugfs" - dri-devel - freedesktop.org experimental mailing list

26 Jun 2020

From: Bhanuprakash Modem bhanuprakash.modem@intel.com
v3:
* Rebase (Manasi)
v2:
* Rebase (Manasi)
As both VRR min and max are already part of drm_display_info,
drm can expose this VRR range for each connector.
Hence this logic should move to core DRM.
This reverts commit 727962f030c23422a01e8b22d0f463815fb15ec4.
