This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers.

Latest version of https://patchwork.freedesktop.org/series/39642/ , hopefully patchwork understands this and doesn't break anything! Lots of changes.

Latest version of PW series 39642, hopefully this should also actually come up on intel-gfx and go through CI. No changes other than rebasing to the current drm-intel-next-queued Lyude Paul (10): drm/atomic: Print debug message on atomic check failure drm/i915: Move DP modeset retry work into intel_dp drm/dp_mst: Fix naming on drm_atomic_get_mst_topology_state() drm/dp_mst: Remove all

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

Next version of https://patchwork.freedesktop.org/series/41576/ All changes in this patch series are just to make checkpatch a little happier, no functional changes.

This is a WIP version of the series I've been working on for a while now to get all of the atomic DRM drivers in the tree to use the atomic MST helpers, and to make the atomic MST helpers actually idempotent. Turns out it's a lot more difficult to do that without also fixing how port and branch device refcounting works so that it actually makes sense, since the current upstream
