Merge branch 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux into drm-next

Initial pull request for DC support.  We've completed a substantial amount of
the cleanup and restructuring in our TODO.  There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes.  Harry made sure all the commits build.  We've enabled DC for vega10
and Raven.  Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.

This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,
Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including
HDMI and DP audio, DP MST, and many other advanced display features.

+

Latest cleanups for DC from you and Harry.  Note that there is some
flickering on some older asics with this branch due to a regression in powerplay
that has already been fixed and will be included in my next non-DC pull request
next week.

* 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux: (897 commits)

AMD DC Display Driver
---------------------
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.
See drivers/gpu/drm/amd/display/TODO for tasks.

===============================================================================
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.
