X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d5586e2f5367829880932c8f057f4df9445056cc;p=linux.git

drm/amd/display: Add debug option for idle reg checks

[Why]
Leave disabled by default due to sequencing issues around power states
where these flags aren't properly reset.

[How]
Allow re-enabling from DC debug option.
