Merge tag 'drm-misc-next-2017-03-06' of git://anongit.freedesktop.org/git/drm-misc into drm-next

First slice of drm-misc-next for 4.12:

Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
  to userspace. I also had the i915 patch in here, but that had a
  small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
  said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
  Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
  Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
  wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
  of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state

Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
  and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
  official, still an experiment, but definitely not complete fail and
  better to avoid confusion. We kinda screwed that up with drm-misc a
  bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over

This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.
