[Intel-gfx] [PATCH v2 0/6] drm/i915/dp_link_training: Define a final failure state when link training fails

[Gil Dekel <gildekel@chromium.org>]

Next version of https://patchwork.freedesktop.org/series/122643/

Reorganize into:
1) Add for final failure state for SST and MST link training fallback.
2) Add a DRM helper for setting downstream MST ports' link-status state.
3) Make handling SST and MST connectors simpler via intel_dp.
4) Update link-status for downstream MST ports.
5) Emit a uevent with the "link-status" trigger property.
