[PATCH v2 0/5] move pstate interface to debugfs
I made a little changes in this series:
1. merge the two last patches together
2. unify the private data interface with the drm debugfs one
now it should be very obvious for a new dev on how to add new files to debugfs
and how to get access to the nouveau structs

[PATCH v2 0/4] drm/dp_mst: Add DP MST debugfs nodes for all drivers
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.
Changes since previous version:

[PATCH 0/2] drm/nouveau: Allow parsing vbios.rom with nvbios from debugfs
This is a small patch series that adds a strap_peek file into our
debugfs, and sets the size of the vbios.rom debugfs file so that nvbios
can easily be used to parse the vbios even on systems where the normal
BIOS retrieval methods (for example, laptops that need ACPI to access
the vbios for the nvidia GPU) won't work. This should make it a little
easier to collect vbioses.

[PATCH v2 0/4] Merge VRAM MM and GEM VRAM source files
VRAM MM and GEM VRAM are only used with each other. This patch set
moves VRAM MM into GEM VRAM source files and cleans up the helper's
public interface.
Version 2 of the patch set doesn't contain functional changes. I'm
reposting due to the rebasing onto the debugfs patches.
v2:
* updated for debugfs support
* fixed typos in comments
