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.

Various pieces of information about DRM formats (number of planes, color
depth, chroma subsampling, ...) are scattered across different helper
functions in the DRM core. Callers of those functions often need to
access more than a single parameter of the format, leading to
inefficiencies due to multiple lookups.
Centralize all format information in a data structure and create a
function to look up information based on the format 4CC.

Adds files and directories to debugfs for controlling and reading frame
CRCs, per CRTC:
dri/0/crtc-0/crc
dri/0/crtc-0/crc/control
dri/0/crtc-0/crc/data
Drivers can implement the set_crc_source callback() in drm_crtc_funcs to
start and stop generating frame CRCs and can add entries to the output
by calling drm_crtc_add_crc_entry.
v2:
- Lots of good fixes suggested by Thierry.
- Added documentation.
- Changed the debugfs layout.
- Moved to allocate the entries circular queue once when frame
generation gets enabled for the first time.
v3:
- Use the control file just to select the source, and start and stop
capture when the data file is opened and closed, respectively.
- Make variable the number of CRC values per entry, per source.
- Allocate entries queue each time we start capturing as now there
isn't a fixed number of CRC values per entry.
- Store the frame counter in the data file as a 8-digit hex number.
- For sources that cannot provide useful frame numbers, place
XXXXXXXX in the frame field.
v4:
- Build only if CONFIG_DEBUG_FS is enabled.
- Use memdup_user_nul.
- Consolidate calculation of the size of an entry in a helper.
- Add 0x prefix to hex numbers in the data file.
- Remove unnecessary snprintf and strlen usage in read callback.
v5:
- Made the crcs array in drm_crtc_crc_entry fixed-size
- Lots of other smaller improvements suggested by Emil Velikov
v7:
- Move definition of drm_debugfs_crtc_crc_add to drm_internal.h
v8:
- Call debugfs_remove_recursive when we fail to create the minor
device
v9:
- Register the debugfs directory for a crtc from
drm_crtc_register_all()
v10:
- Don't let debugfs failures interrupt CRTC registration (Emil
Velikov)
v11:
- Remove extra brace that broke compilation. Sorry!

like a bad idea since it requires making drm_mode_crtc_set_obj_prop
non-static. But eventually that will get split away too (like
the connector version already is) for both crtc and planes. Hence I
reconsidered.
- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
renaming the drm_modeset.h header I already started building up.
This is more consistent (matches the name of the main structure),
and I want to be able to use drm_modeset.[hc] for the basic modeset
init/cleanup functionality like drm_mode_config_init.

Same treatment as before. Only hiccup is drm_crtc_mask, which
unfortunately can't be resolved until drm_crtc.h is less of a monster.
Untangle the header loop with a forward declaration for that static
inline.

Everyone knows them, except all the new folks joining from the ARM
side haven't lived through all the pain of the past years and are
entirely surprised when I raise this. Definitely time to document
this.
Last time this was a big discussion was about 6 years ago, when qcom
tried to land a kernel driver without userspace. Dave Airlie made the
rules really clear:

No actual text changes except that I did polish the kerneldoc a bit,

- Shuffle docs from drm-kms.rst into the structure docs where it makes
sense.

One thing I've changed is around probing: Old docs says that you
_must_ use the probe helpers, which isn't correct. Helpers are always
optional.

There's not much point in kerneldoc if it's not included:
- It won't show up in the pretty html pages.
- The comments itself won't get parsed, which means 0day won't pick up
changes, resulting in stale docs fast.
Also, uapi really should be core, not helpers, so move drm_blend.c to
that. That also means that the zpos normilize function loses it's
helper status (and we might as well call it always). For that,
EXPORT_SYMBOL. Just spotted while integrating docs and noticing that
one was missing.
With sphinx there's really no excuse any more to not build the docs
and make sure it's all nice!

Pulls in quite a lot of connector related structures (cmdline mode,
force/status enums, display info), but I think that all makes perfect
sense.
Also had to move a few more core kms object stuff into drm_modeset.h.
And as a first cleanup remove the kerneldoc for the 2 connector IOCTL
- DRM core docs are aimed at drivers, no point documenting internal in
excruciating detail.
v2: And also pull in all the connector property code.

Also start with drm_modeset.h with the core bits, since we need

- Readjust headings - we lost one level through the extraction into a
separate .rst file.
- Merge helper reference sections with the helper documentation - that
split was just an artifact of the docbook toolchain sucking at too
deep nesting levels. No such problems with sphinx.
- Move the cma helpers in with the gem documentation, since they're
helpers to implement gem using CMA/dma memory as a backend.
