[PATCH 0/3] Adding DC debug options

To facilitate bringup of new ASICs, debugging, and measuring of
various power features we would like the ability to disable them
as needed.

This differs from dcfeaturemask in that dcfeaturemask is a collection
of experimental features that can't be enabled by default, whereas
dcdebugmask is a collection of features that are enabled by default.

Harry Wentland (3):
  drm/amd/display: Add DC Debug mask to disable features for bringup
  drm/amd/display: Fix disable_stutter debug option
  drm/amd/display: Respect PP_STUTTER_MODE but don't override
    DC_DISABLE_STUTTER
