Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.11.
Nothing too major, the tinydrm and mmu-less support should make
writing smaller drivers easier for some of the simpler platforms, and
there are a bunch of documentation updates.
Intel grew displayport MST audio support which is hopefully useful to
people, and FBC is on by default for GEN9+ (so people know where to
look for regressions). AMDGPU has a lot of fixes that would like new
firmware files installed for some GPUs.
Other than that it's pretty scattered all over.
I may have a follow up pull request as I know BenH has a bunch of AST
rework and fixes and I'd like to get those in once they've been tested
by AST, and I've got at least one pull request I'm just trying to get
the author to fix up.

The format of the structure references in device_link.rst is
incorrect, because it doesn't cause proper references to the
struct data types to be generated (for struct dev_pm_domain in
particular).
Fix that by using the :c:type:`struct name <name>` convention
for encoding references to struct data types.

There is a better way to represent structure references than it was
done in device.rst by commit 730c4c0530 (PM / sleep / docs: Convert
PM notifiers document to reST), which is to use "struct name" as a
link caption (e.g. :c:type:`struct device <device>`). That will
cause sphinx to generate a proper reference to the data type in
question (struct device in the example above) and "struct name"
will work as the link in the HTML output.
Fix device.rst by using that convention where applicable.

Convert deviceiobook.tmpl to RST and incorporate it into the driver API

Like the rest of our documentation, this one could use some work. There's
no mention of ioremap() and friends, no mention of io_read*() and friends.
But we have nice documentation for all those folks writing new drivers that
do port I/O :).
The :c:func: notation has been left off of all the read*/write* functions.
There's no kerneldoc comments for them anyway, so those links will never be
live, and writing a bunch of repetitive "read a byte from I/O memory"
comments lacks appeal.

First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
dma-buf kerneldoc patches
It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during
this time might be useful.
I'd also like to backmerge -rc2+this into drm-intel next week, we have
quite a pile of patches waiting for the stuff in here.

Just prep work to polish and consolidate all the dma-buf related
documenation.
Unfortunately I didn't discover a way to both integrate this new file
into the overall toc while keeping it at the current place. Work
around that by moving it into the overall driver-api/index.rst.

Put this documentation with the other driver docs and try to keep the top
level reasonably clean.

Few files under dma-buf/ changed their names but the changes didn't
applied to a document that referencing them. It is causing few
documentation build warnings. This commit fixes the problems by
applying changed file names on the document.

Add minimal conf.py makes the driver-api folder buildable
stand-alone. To build only this folder run::
make SPHINXDIRS=driver-api htmldocs
make SPHINXDIRS=driver-api pdfdocs

Perform a relatively simple conversion of vme_api.txt to reStructuredText
and move under driver-api, which seems the most logical place for this
documentation.

It never made sense to keep these documents together; move each into its
own file.
Drop the section numbering on hsi.txt on its way to its own file.

The HSI subsystem documentation was split across hsi.txt and the
device-drivers docbook. Now that the latter has been converted to Sphinx,
pull in the HSI document so that it's all in one place.

We don't need to keep it as a single large file anymore; split it up so
that it is easier to manage and the individual sections can be read
directly as plain files.
