[PATCH 0/2] drm/nouveau: Add support for dp_mst_info in debugfs
This hooks up the DRM helpers for dumping information on the current
status of each MST topology from nouveau's perspective to debugfs files,
similar to what i915 does (albeit, i915 labels their debugfs node for
this as i915_dp_mst_info).

[PATCH 0/2] Fix display detection issues with P50-P52 docks
This fixes some annoying issues on the P50-P52 with displays not being
detected if they aren't plugged in at boot, and sometimes even when they
are plugged in at boot.
See: https://bugzilla.redhat.com/show_bug.cgi?id=1477182
