The files under Documentation/ABI should follow the syntax
as defined at Documentation/ABI/README.Allow checking if they're following the syntax by running
the ABI parser script on COMPILE_TEST.With that, when there's a problem with a file under
Documentation/ABI, it would produce a warning like:Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#14:

Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

The Sphinx build system for PDF is too complex and generate
lots of ancillary files, including one PDF file for each
image.So, at the end, the main latex dir has 156 pdf files, instead
of the 71 ones that would match each generated book. That's
confusing and it makes harder to identify when something didn't
work.So, instead, let's move the final PDF output(s) to a separate
dir. This way, the latex/ dir will have the temporary and the
final *.tex files, while the final pdf files that built ok
will be under the pdf/ directory.Signed-off-by: Mauro Carvalho Chehab

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.Signed-off-by: Mauro Carvalho Chehab

Rasmus correctly observed that the existing jobserver reservation only
worked if no other build targets were specified. The correct approach
is to hold the jobserver slots until sphinx has finished. To fix this,
the following changes are made:- refactor (and rename) scripts/jobserver-exec to set an environment
variable for the maximally reserved jobserver slots and exec a
child, to release the slots on exit.- create Documentation/scripts/parallel-wrapper.sh which examines both
$PARALLELISM and the detected "-jauto" logic from Documentation/Makefile
to decide sphinx's final -j argument.- chain these together in Documentation/Makefile

While sphinx 1.7 and later supports "-jauto" for parallelism, this
effectively ignores the "-j" flag used in the "make" invocation, which
may cause confusion for build systems. Instead, extract the available
parallelism from "make"'s job server (since it is not exposed in any
special variables) and use that for the "sphinx-build" run. Now things
work correctly for builds where -j is specified at the top-level:make -j16 htmldocs
If -j is not specified, continue to fallback to "-jauto" if available.

Since Sphinx version 1.7, it is possible to use "-jauto" in
order to speedup documentation builds. On older versions,
while -j was already supported, one would need to set the
number of threads manually.So, if SPHINXOPTS is not provided, add -jauto, in order to
speed up the build. That makes it *a lot* times faster than
without -j.If one really wants to slow things down, it can just use:
make SPHINXOPTS=-j1 htmldocs

[ jc: fixed perl magic to determine sphinx version ]
Signed-off-by: Jonathan Corbet -
Call the script every time a make docs target is selected, on
a simplified check mode.With this change, the script will set two vars:
$min_version - obtained from `needs_sphinx` var inside
conf.py (currently, '1.3')$rec_version - obtained from sphinx/requirements.txt.
With those changes, a target like "make htmldocs" will do:
1) If no sphinx-build/sphinx-build3 is found, it will run
the script on normal mode as before, checking for all
system dependencies and providing install hints for the
needed programs and will abort the build;2) If no sphinx-build/sphinx-build3 is found, but there is
a sphinx_${VER}/bin/activate file, and if
${VER} >= $min_version (string comparation), it will
run in full mode, and will recommend to activate the
virtualenv. If there are multiple virtualenvs, it
will string sort the versions, recommending the
highest version and will abort the build;3) If Sphinx is detected but has a version lower than
$min_version, it will run in full mode - with will
recommend creating a virtual env using sphinx/requirements.txt,
and will abort the build.4) If Sphinx is detected and version is lower than
$rec_version, it will run in full mode and will
recommend creating a virtual env using sphinx/requirements.txt.In this case, it **won't** abort the build.
5) If Sphinx is detected and version is equal or righer than
$rec_version it will return just after detecting the
version ("quick mode"), not checking if are there any
missing dependencies.Just like before, if one wants to install Sphinx from the
distro, it has to call the script manually and use `--no-virtualenv`
argument to get the hints for his OS:You should run:
sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme
While here, add a small help for the three optional arguments
for the script.Signed-off-by: Mauro Carvalho Chehab

In the past, Sphinx was generating a LaTex Makefile that would
run xelatex 3 times. Running it multiple times is needed in order
to make the indexes right.However, newer versions of it runs it just once, as it expects
the machine to use the "latexmk" build, with automatically
detects the need for rebuilds.So, add a logic at the Makefile in order to detect if latexmk
is installed. If so, it will call it.As an additional bonus, the output of latexmk is a little bit
better, making easier to identify build problems.Signed-off-by: Mauro Carvalho Chehab

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.Check DT binding schema documents:
make dt_binding_checkBuild dts files and check using DT binding schema:
make dtbs_checkOptionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.Cc: Jonathan Corbet

Add a simple script and build target to do a treewide grep for
references to files under Documentation, and report the non-existing
file in stderr. It tries to take into account punctuation not part of
the filename, and wildcards, but there are bound to be false positives
too. Mostly seems accurate though.We've moved files around enough to make having this worthwhile.
