Pull amdgpu DC display code for Vega from Dave Airlie:
 "This is the pull request for the AMD DC (display code) layer which is
  a requirement to program the display engines on the new Vega and Raven
  based GPUs. It also contains support for all amdgpu supported GPUs
  (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic
  modesetting compatible driver (unlike the current in-tree display
  code).

  I've kept it separate from drm-next because it may have some things
  that cause you to reject it.

  Background story:

  AMD have an internal team creating a shared OS codebase for display at
  hw bring up time using information from their hardware teams. This
  process doesn't lead to the most Linux friendly/looking code but we
  have worked together on cleaning a lot of it up and dealing with
  sparse/smatch/checkpatch, and having their team internally adhere to
  Linux coding standards.

  This tree is a complete history rebased since they started opening it,
  we decided not to squash it down as the history may have some value.
  Some of the commits therefore might not reach kernel standards, and we
  are steadily training people in AMD to better write commit msgs.

  There is a major bunch of generated bandwidth calculation and
  verification code that comes from their hardware team. On Vega and
  before this is float calculations, on Raven (DCN10) this is double
  based. They do the required things to do FP in the kernel, and I could
  understand this might raise some issues. Rewriting the bandwidth would
  be a major undertaken in reverification, it's non-trivial to work out
  if a display can handle the complete set of mode information thrown at
  it.

  Future story:

  There is a TODO list with this, and it address most of the remaining
  things that would be nice to refine/remove. The DCN10 code is still
  under development internally and they push out a lot of patches quite
  regularly and are supporting this code base with their display team. I
  think we've reached the point where keeping it out of tree is going to
  motivate distributions to start carrying the code, so I'd prefer we
  get it in tree. I think this code is slightly better than STAGING
  quality but not massively so, I'd really like to see that float/double
  magic gone and fixed point used, but AMD don't seem to think the
  accuracy and revalidation of the code is worth the effort"
