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"

+AMD DC is the display driver for AMD devices starting with Vega. There has been
+a bunch of progress cleaning it up but there's still plenty of work to be done.

+===============================================================================
+TODOs
+===============================================================================
+
+1. Base this on drm-next - WIP
+
+
+2. Cleanup commit history
+
+
+3. WIP - Drop page flip helper and use DRM's version
+
+
+4. DONE - Flatten all DC objects
+    * dc_stream/core_stream/stream should just be dc_stream
+    * Same for other DC objects
+
+    "Is there any major reason to keep all those abstractions?
+
+    Could you collapse everything into struct dc_stream?
+
+    I haven't looked recently but I didn't get the impression there was a
+    lot of design around what was public/protected, more whatever needed
+    to be used by someone else was in public."
+    ~ Dave Airlie
+
+
+5. DONE - Rename DC objects to align more with DRM
+    * dc_surface -> dc_plane_state
+    * dc_stream -> dc_stream_state
+
+
+6. DONE - Per-plane and per-stream validation
+
+
+7. WIP - Per-plane and per-stream commit
+
+
+8. WIP - Split pipe_ctx into plane and stream resource structs
+
+
+9. Attach plane and stream reources to state object instead of validate_context
+
+
+10. Remove dc_edid_caps and drm_helpers_parse_edid_caps
+    * Use drm_display_info instead
+    * Remove DC's edid quirks and rely on DRM's quirks (add quirks if needed)
+
+    "Making sure you use the sink-specific helper libraries and kernel
+    subsystems, since there's really no good reason to have 2nd
+    implementation of those in the kernel. Looks likes that's done for mst
+    and edid parsing. There's still a bit a midlayer feeling to the edid
+    parsing side (e.g. dc_edid_caps and dm_helpers_parse_edid_caps, I
+    think it'd be much better if you convert that over to reading stuff
+    from drm_display_info and if needed, push stuff into the core). Also,
+    I can't come up with a good reason why DC needs all this (except to
+    reimplement half of our edid quirk table, which really isn't a good
+    idea). Might be good if you put this onto the list of things to fix
+    long-term, but imo not a blocker. Definitely make sure new stuff
+    doesn't slip in (i.e. if you start adding edid quirks to DC instead of
+    the drm core, refactoring to use the core edid stuff was pointless)."
+    ~ Daniel Vetter
+
+
+11. Remove dc/i2caux. This folder can be somewhat misleading. It's basically an
+overy complicated HW programming function for sendind and receiving i2c/aux
+commands. We can greatly simplify that and move it into dc/dceXYZ like other
+HW blocks.
+
+12. drm_modeset_lock in MST should no longer be needed in recent kernels
+    * Adopt appropriate locking scheme
+
+13. get_modes and best_encoder callbacks look a bit funny. Can probably rip out
+a few indirections, and consider removing entirely and using the
+drm_atomic_helper_best_encoder default behaviour.
+
+14. core/dc_debug.c, consider switching to the atomic state debug helpers and
+moving all your driver state printing into the various atomic_print_state
+callbacks. There's also plans to expose this stuff in a standard way across all
+drivers, to make debugging userspace compositors easier across different hw.
+
+15. Move DP/HDMI dual mode adaptors to drm_dp_dual_mode_helper.c. See
+dal_ddc_service_i2c_query_dp_dual_mode_adaptor.
+
+16. Move to core SCDC helpers (I think those are new since initial DC review).
+
+17. There's still a pretty massive layer cake around dp aux and DPCD handling,
+with like 3 levels of abstraction and using your own structures instead of the
+stuff in drm_dp_helper.h. drm_dp_helper.h isn't really great and already has 2
+incompatible styles, just means more reasons not to add a third (or well third
+one gets to do the cleanup refactor).
+
+18. There's a pile of sink handling code, both for DP and HDMI where I didn't
+immediately recognize the standard. I think long term it'd be best for the drm
+subsystem if we try to move as much of that into helpers/core as possible, and
+share it with drivers. But that's a very long term goal, and by far not just an
+issue with DC - other drivers, especially around DP sink handling, are equally
+guilty.
+
+19. The DC logger is still a rather sore thing, but I know that the DRM_DEBUG
+stuff just isn't up to the challenges either. We need to figure out something
+that integrates better with DRM and linux debug printing, while not being
+useless with filtering output. dynamic debug printing might be an option.
+
+20. Use kernel i2c device to program HDMI retimer. Some boards have an HDMI
+retimer that we need to program to pass PHY compliance. Currently that's
+bypassing the i2c device and goes directly to HW. This should be changed.
