This is the large series for adding MST suspend/resume reprobing that I've been working on for quite a while now. In addition, I: - Refactored and cleaned up any code I ended up digging through in the process of understanding how some parts of these helpers worked. - Added some debugging tools along the way that I ended up needing to figure out some issues in my own code Note that

Since we're going to be reprobing the entire topology state on resume now using sideband transactions, we need to ensure that we actually have short HPD irqs enabled before calling drm_dp_mst_topology_mgr_resume().

Latest version of PW series 39642, hopefully this should also actually come up on intel-gfx and go through CI.

Next version of https://patchwork.freedesktop.org/series/41576/ Only changes are removing duplicate SoBs that git send-email annoyingly added.
