Subject: [PATCH 0/6] Implement proper MST fallback retraining in i915
Date:   Thu,  8 Mar 2018 18:24:14 -0500

This is the first version of my patch series to implement MST fallback
retraining in i915, along with improving the stability of i915's mst
retraining in general. Additionally, it also introduces helpers into DRM
to help with correctly handling MST fallback retraining so that other
drivers may also implement it. If your driver has a homegrown
implementation of this, you should convert it to these helpers to ensure
that the behavior of atomic commits and connector's link status
properties in the event of requiring retraining on an MST topology
remains consistent between DRM drivers.

Additionally, this lets me use the DisplayPort on my dock so I can
finally free up the thunderbolt 3 connector on it for more useful
things. At long last :).
