Mauro Carvalho Chehab 6e862f3cbb [media] diff-v4l.rst: Fix V4L version 1 references
The V4L version 1 structures had long gone from the Linux Kernel.
It doesn't make sense to use cross-references for them, as they

So, get rid of them.

Mauro Carvalho Chehab e8be7e97e6 [media] docs-rst: convert uAPI structs to C domain
instead of declaring the uAPI structs using usual refs, e. g.:
	.. _foo-struct:

Use the C domain way:
	.. c:type:: foo_struct

This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.

That solves about ~100 undefined warnings like:
	WARNING: c:type reference target not found: foo_struct

That was specified by the sYCC spec and it makes sense to use this
across the board.

Nick Dyer b2fe22d0cf [media] v4l2-core: Add support for touch devices
Some touch controllers send out touch data in a similar way to a
greyscale frame grabber.

Add new device type VFL_TYPE_TOUCH:
- This uses a new device prefix v4l-touch for these devices, to stop
  generic capture software from treating them as webcams. Otherwise,
  touch is treated similarly to video capture.
- Add V4L2_INPUT_TYPE_TOUCH
- Add MEDIA_INTF_T_V4L_TOUCH
- Add V4L2_CAP_TOUCH to indicate device is a touch device

Add formats:
- V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas
- V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas
- V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data
- V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data

This support will be used by:
- Atmel maXTouch (atmel_mxt_ts)
- Synaptics RMI4.
- sur40

This is broken when it is used inside a \begin{alltt} block.

it is one of the fallback methods for it.

With this change the indirection using ":ref:`CEC_DQEVENT` is no longer
needed, we can refer the ioctl directly with ":c:func:`CEC_DQEVENT`". As
addition in the index, there is a entry "CEC_DQEVENT (C function)".

Currently if none of the requested logical addresses can be claimed, the
framework will fall back to the Unregistered logical address.

Add a flag to enable this explicitly. By default it will just go back to
the unconfigured state.

Usually Unregistered is not something you want since the functionality is
very limited. Unless the application has support for this, it will fail
to work correctly. So require that the application explicitly requests
this.

The first one would fit into one page, but the latex.py logic

The second one is really big, and won't fit on a single page.

Mauro Carvalho Chehab 0c04622162 [media] extended-controls.rst: avoid going past page with LaTeX
It is painful to put code/verbatim code in bold. It seems that
the only way is to arrange it like:
	``foo``
	    bar

At least on LaTeX output, when this happens, the "foo" string
is not hidentable/breakable. The entire string should fit into
a single line.

Add a workaround for this ReST limitation by splitting the
foo string into two strings, on separate lines. The output
is not the best, but it works.

There are, however, two exceptions: RGB and YUV big tables,

those are long tables, but not really sure.

Mauro Carvalho Chehab 5bd4bb7817 [media] docs-rst: add tabularcolumns to all tables
LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.

As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:

my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
	if (!$table_header) {
		$has_cols = 1 if (m/..\s+tabularcolumns::/);
		if (m/..\s+flat-table::/) {
			$table_header = 1;
			$header = $_;
			next;
		}
		$out .= $_;
		next;
	}
	$header .= $_;
	@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
	if (m/^\n$/) {
		if (!$has_cols && @widths) {
			my ($tot, $t, $i) = (0, 0, 0);
			foreach my $v(@widths) { $tot += $v; };
			$out .= ".. tabularcolumns:: |";
			for ($i = 0; $i < scalar @widths - 1; $i++) {
				my $v = $widths[$i];
				my $w = round(10 * ($v * $line_size) / $tot) / 10;
				$out .= sprintf "p{%.1fcm}|", $w;
				$t += $w;
			}
			my $w = $line_size - $t;
			$out .= sprintf "p{%.1fcm}|\n\n", $w;
		}
		$out .= $header;
		$table_header = 0;
		$has_cols = 0;
		$header = "";

Mauro Carvalho Chehab d888f8d7d8 [media] doc-rst: Fix license for the media books
The kAPI, v4l-drivers and dvb-drivers never used the
GNU FDL license. The addition of such license header were
just due to copy-and-paste. So, let's fix it.

As the media_kapi were part of device-drivers.tmp, it is
under GPL v2+.

The other two books is an agregation of files without any
license explicitly specified. So, they're all bound to the
Kernel's COPYING license. So, they're GPL v2 only.

Mauro Carvalho Chehab ef88f10eb8 [media] doc-rst: backward compatibility with older Sphinx versions
Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!

As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the
table of contents. Do that by using a css class.

There were several files under Documentation/video4linux/bttv.

Instead of simply copying them to the rst folder, I opted to
merge into a single document and adjust the headers to
adjust the section levels and fix the cards tables.

There are two exceptions on the merge:

- The Tuners were renamed as a separate document, as they
  describe a separate driver;

- I removed the PROBLEMS section. It describes problems with
  the very first generation of 3D boards (Mistique/S3).
  It sounds very unlikely that someone would still need to
  install a bttv board on such hardware. Also, it is not
  very well written, IMHO.
