[PATCH 64/81] drm/amd/display: Get freesync properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Harry Wentland <harry.wentland@xxxxxxx>

Eventually we should create proper atomic properties for freesync
but currently freesync is broken and we still have the legacy
properties. Simply return the legacy properties.
