Add DisplayPort CEC-Tunneling-over-AUX support to nouveau.

From: Hans Verkuil <hans.verkuil at cisco.com> Repost because I wasn't a member of the nouveau mailinglist the first time around and this series was blocked. I also updated this cover letter for the part about the amdgpu patch after receiving feedback from Alex Deucher. The patches are unchanged (except for adding Alex' Acked-by to the amdgpu patch). Now that the DisplayPort

From: Hans Verkuil <hans.verkuil at cisco.com> Now that the DisplayPort CEC-Tunneling-over-AUX drm+i915 support has been merged in the mainline kernel it is time to roll this out to nouveau and amdgpu as well. I combined both in the same patch series since both depend on the same first patch, the comments in this cover letter apply to both and the implementation is also very similar (and

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
