Mauro Carvalho Chehab 74604b7390 [media] doc-rst: Fix conversion for MC core functions
There were lots of issues at the media controller side,
after the conversion:

- Some documentation at the header files weren't using the
  kernel-doc start block;

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- Fix the cross-references at the media controller description.

Mauro Carvalho Chehab 89cb3ddbe7 [media] doc-rst: Fix conversion for v4l2 core functions
The conversion from DocBook lead into some conversion issues,
basically due to the lack of proper support at kernel-doc.

So, address them:

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- kernel-doc doesn't escape things like *pointer, so we
  need to manually add a escape char before it.

- On some cases, kernel-doc conversion requires violating
  the 80-cols, as otherwise it won't properly parse the
  source code.

Mauro Carvalho Chehab 684ffa2d55 [media] doc-rst: split media_drivers.rst into one file per API type
Just like the uAPI book is split into parts, let's split the
kAPI documentation. That should make easier to maintain, and
will split the final documentation into smaller html files.

Mauro Carvalho Chehab d26a5d4350 [media] doc-rst: Convert media API to rst
Move the contents of the media section at
DocBooks/DocBook/device-drivers.tmpl to a new ReST book.

For now, the contents is kept as-is. Next patches will fix
the warnings and add cross-references that were removed due to
the conversion.

Mauro Carvalho Chehab 520a247760 doc-rst: Fix compilation of the pdf docbook
The rst2pdf tool is a very broken toolchain, with is not capable
of parsing complex documents. As such, it doesn't build the
media book, failing with:

	[ERROR] pdfbuilder.py:130 too many values to unpack

(using rst2pdf version 0.93.dev-r0 and Sphinx version 1.4.5)

So, make it build only the books we know that are safe to build.

Btw, with the standard Sphinx version shipped on Fedora 24 (Sphinx
1.3.1), rst2pdf doesn't build even the simple kernel-documentation,
failing with this error:
    writing Kernel... [ERROR] pdfbuilder.py:130 list index out of range

This is a known bug:
    https://github.com/sphinx-doc/sphinx/issues/1844

So, maybe we should just disable pdf generation from RST for good,
as I suspect that maintaining it with a broken toolchain will be a
big headache.

Mauro Carvalho Chehab e6e9c9b238 [media] docs-rst: Fix some typos
Those fixes came from patchs from Andrea for the old DocBook
documentation.

As we're removing it on Kernel 4.8, it doesn't make sense to
apply the original patches, but, as the typos were ported
to ReST, let's fix the issues there.

Mauro Carvalho Chehab ab7a85a7d0 [media] doc-rst: increase depth of the main index
It is useful to have an index with all the book contents somewhere,
as it makes easier to seek for something. So, increase maxdepth
to 5 for the main index at the beginning of the book.

While here, remove the genindex content, as it is bogus.

Hans Verkuil d2cd627be0 [media] doc-rst: update CEC_RECEIVE
The timestamp field was split into rx_ts and tx_ts, and the rx/tx_status
fields were moved. Update the doc accordingly.

Also fix a bug that stated that a non-zero tx_status field signaled an
error. That's not true, since TX_STATUS_OK is 1, not 0.
