a0634663d0 drm/nouveau: Do not set struct drm_mode_config_funcs.output_poll_changed 
The output_poll_changed hook was only necessary before in-kernel
DRM clients existed, but is now obsolete. The client code handles
display hotplugging internally.

v2:

6901f1d647 drm/nouveau: move nvxx_* definitions to nouveau_drv.h 
These are some dodgy "convenience" macros for the DRM driver to peek
into NVKM state.  They're still used in a few places, but don't belong
in nvif/device.h in any case.

Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm
instead of an nvif_device.

v2:
- use drm->nvkm pointer for nvxx_*() macros, removing some void*
v3:
- add some explanation of the nvxx_*() macros

There's no good reason the ioremap() that results from nvif_object_map()
should fail, so add a check that the map succeeded, and remove the rd/wr

As this was the last user of rd/wr methods, the nvif plumbing is removed
at the same time.

bf32a3a126 drm/nouveau: use GEM references instead of TTMs 
TTM wants to get rid of the duplicate refcounting of the embedded GEM
object and its own reference count.

Hence, use of GEM object references where possible.

Also get rid of nouveau_bo_ref() and replace it with nouveau_bo_fini(),
which drops the initial reference we get from initializing a ttm_bo.

e0f04e41e8 drm/atomic-helpers: Invoke end_fb_access while owning plane state 
Invoke drm_plane_helper_funcs.end_fb_access before
drm_atomic_helper_commit_hw_done(). The latter function hands over
ownership of the plane state to the following commit, which might
free it. Releasing resources in end_fb_access then operates on undefined
state. This bug has been observed with non-blocking commits when they
are being queued up quickly.

Here is an example stack trace from the bug report. The plane state has
been free'd already, so the pages for drm_gem_fb_vunmap() are gone.

Unable to handle kernel paging request at virtual address 0000000100000049
[...]
 drm_gem_fb_vunmap+0x18/0x74
 drm_gem_end_shadow_fb_access+0x1c/0x2c
 drm_atomic_helper_cleanup_planes+0x58/0xd8
 drm_atomic_helper_commit_tail+0x90/0xa0
 commit_tail+0x15c/0x188
 commit_work+0x14/0x20

Fix this by running end_fb_access immediately after updating all planes
in drm_atomic_helper_commit_planes(). The existing clean-up helper
drm_atomic_helper_cleanup_planes() now only handles cleanup_fb.

For aborted commits, roll back from drm_atomic_helper_prepare_planes()
in the new helper drm_atomic_helper_unprepare_planes(). This case is
different from regular cleanup, as we have to release the new state;
regular cleanup releases the old state. The new helper also invokes
cleanup_fb for all planes.

The changes mostly involve DRM's atomic helpers. Only two drivers, i915
and nouveau, implement their own commit function. Update them to invoke
drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail
function do not require changes.

v4:
	* fix documentation (kernel test robot)
v3:
	* add drm_atomic_helper_unprepare_planes() for rolling back
	* use correct state for end_fb_access
v2:
	* fix test in drm_atomic_helper_cleanup_planes()

191dc43935 drm/dp_mst: Store the MST PBN divider value in fixed point format 
On UHBR links the PBN divider is a fractional number, accordingly store
it in fixed point format. For now drm_dp_get_vc_payload_bw() always
returns a whole number and all callers will use only the integer part of
it which should preserve the current behavior. The next patch will fix
drm_dp_get_vc_payload_bw() for UHBR rates returning a fractional number
for those (also accounting for the channel coding efficiency correctly).

7707dd6022 drm/dp_mst: Fix fractional DSC bpp handling 
The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.

And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.

v2:
- Fix DSC kunit test cases.

a4ead6e37e drm/nouveau/kms/nv50: hide unused variables 
After a recent change, two variables are only used in an #ifdef:

drivers/gpu/drm/nouveau/dispnv50/disp.c: In function 'nv50_sor_atomic_disable':
drivers/gpu/drm/nouveau/dispnv50/disp.c:1569:13: error: unused variable 'ret' [-Werror=unused-variable]
 1569 |         int ret;
      |             ^~~
drivers/gpu/drm/nouveau/dispnv50/disp.c:1568:28: error: unused variable 'aux' [-Werror=unused-variable]
 1568 |         struct drm_dp_aux *aux = &nv_connector->aux;
      |                            ^~~

Move them into the same conditional block, along with the nv_connector variable
that becomes unused during that fix.
