This patchset does some cleaning up of the atomic VCPI helpers for MST, and converts nouveau over to using them. I would have included amdgpu in this patch as well, but at the moment moving them over to the atomic helpers is nontrivial.

This is 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 implementation requires a

Most of the reason I'm asking for an RFC here is because this code pulls a lot of code out of i915 and into shared DP helpers. Anyway-nouveau's HPD related code has been collecting dust for a while. Other then the occasional runtime PM related and MST related fixes, we're missing a lot of nice things that have been added to DRM since this was originally written. Additionally, the code
