I totally butcherd the job on typing the kernel-doc for these, and no
one realized. Noticed by Russell. Maarten has a more complete approach
to this confusion, by making it more explicit what the new/old state
is, instead of this magic switching behaviour.
v2:
- Liviu pointed out that wait_for_fences is even more magic. Leave
that as @state, and document @pre_swap better.
- While at it, patch in header for the reference section.
- Fix spelling issues Russell noticed.
v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/,
since async flip is something else than non-blocking.

It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.
Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.
For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.
Mostly a cocci job, with a bit of manual stuff mixed in.

Looking at the ioctl permission checks I noticed that it's impossible
to import gem buffers into a control nodes, and fd2handle/handle2fd
also don't work, so no joy with dma-bufs.
The only way to do anything with a control node is by drawing stuff
into a dumb buffer and displaying that. I suspect control nodes are an
entirely unused thing, and a cursory check shows that there does not
seem to be any callers of drmOpenControl nor of the other drmOpen
functions using DRM_MODE_CONTROL.
Since I don't like dead uabi, let's remove it. But since this would be
a really big change I think it's better to start out small by simply
not registering anything. We can garbage-collect the dead code later
on, once we're sure it's really not used anywhere.

Support DRM out-fences by creating a sync_file with a fence for each CRTC
that sets the OUT_FENCE_PTR property.
We use the out_fence pointer received in the OUT_FENCE_PTR prop to send

The sync_file and fd are allocated/created before commit, but the
fd_install operation only happens after we know that commit succeed.

There is now a new property called IN_FENCE_FD attached to every plane
state that receives sync_file fds from userspace via the atomic commit
IOCTL.
The fd is then translated to a fence (that may be a fence_array
subclass or just a normal fence) and then used by DRM to fence_wait() for
all fences in the sync_file to signal. So it only commits when all
framebuffers are ready to scanout.

Reference from drm_dp_aux description (about transfer):
Upon success, the implementation should return the number of payload bytes
that were transferred, or a negative error-code on failure. Helpers
propagate errors from the .transfer() function, with the exception of
the -EBUSY error, which causes a transaction to be retried. On a short,
helpers will return -EPROTO to make it simpler to check for failure.
The analogix_dp_transfer will return num_transferred, but if there is none
byte been transferred, the return value will be 0, which means success, we
should return error-code if transfer none byte.

drm/amdgpu: add display controller implementation for si v10
Realign it with later display code. Tsk, tsk for massive copypasting

And also put the overview section into the KMS Properties part of the
docs, instead of randomly-placed within the helpers - this is part of
the uabi.
With this patch I think drm_crtc.[hc] is cleaned up and entirely
documented.

And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now
only contains CRTC-related functions and structures.
v2:
- rebase onto drm-misc
- don't forget to move drm_mode_config_cleanup.
- move 2 internal decls under the right heading (Chris)

This reverts commit 6dffd431e2.
Adding new mode flags willy nilly breaks existing userspace. We need to
coordinate this better, potentially with a new client cap that only
exposes the aspect ratio flags when userspace is prepared for them
(similar to what we do with stereo 3D modes).
This also broke things so that we would always send out VIC==0 in
the AVI infoframe unless the user specified an aspect ratio via
the mode flags. And the automagic RGB full vs. limited range
handling was similartly broken as the user mode would never match
any CEA mode.

kerneldoc expects the comment next to definitions, otherwise it can't
pick up exported vs. internal stuff.
This fixes a warning from the doc build done with:

I want to move dumb buffer documentation into the right vfuncs, and
for that I first need to be able to pull that into kerneldoc without
having to clean up all of drmP.h. Also, header-splitting is nice.
While at it shuffle all the function declarations for drm_drv.c into
the right spots, and drop the kerneldoc for drm_minor_acquire/release
since it's only used internally.
v2: Keep all existing copyright notices (Chris).

Would be great if everony could add

not sure why it failed to spot this.

kbuild spotted this error, with drm/msm patches that add a new
modeset-lock in the driver and driver built as a module:
ERROR: "crtc_ww_class" [drivers/gpu/drm/msm/msm.ko] undefined!
Really the only reason for crtc_ww_class not being internal to
drm_modeset_lock.c is that drm_modeset_lock_init() was static-inline
(for no particularly good reason).
Fix that, and move crtc_ww_class into drm_modeset_lock.c.
