The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the
SYCC define is about to be removed for use in the kernel we need to
drop it in the TPG code as well.
This patch also adds a 4th decimal to the 601 conversion matrix.
That was specified by the sYCC spec and it makes sense to use this
across the board.

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.

The Sphinx 1.4.x definition for \DUrole is:

This is broken when it is used inside a \begin{alltt} block.
So, replace it by just "#2", as this won't cause troubles, and
it is one of the fallback methods for it.

This is only one example, demonstrating the benefits of the patch
series. The CEC_DQEVENT ioctl is migrated to the sphinx c-domain and
referred by ":name: CEC_DQEVENT".
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)".

Moved the *duplicate C object description* warnings for function
declarations in the nitpicky mode. In nitpick mode, you can suppress
those warnings (e.g. ioctl) with::
nitpicky = True
nitpick_ignore = [
("c:func", "ioctl"),
]
See Sphinx documentation for the config values for ``nitpick`` and
``nitpick_ignore`` [1].
With this change all the ".. cpp:function:: int ioctl(..)" descriptions
(found in the media book) can be migrated to ".. c:function:: int
ioctl(..)", without getting any warnings. E.g.::
.. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp )
.. c:function:: int ioctl( int fd, int request, struct cec_event *argp )
The main effect, is that we get those *CPP-types* back into Sphinx's C-
namespace and we need no longer to distinguish between c/cpp references,
when we refer a function like the ioctl.

the ref-name of a function can be modified. E.g.::
.. c:function:: int ioctl( int fd, int request )
:name: VIDIOC_LOG_STATUS
The func-name (e.g. ioctl) remains in the output but the ref-name
changed from ``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for
this function is also changed to ``VIDIOC_LOG_STATUS`` and the function
can now referenced by::
:c:func:`VIDIOC_LOG_STATUS`

There are two big tables here that are very hard to adjust its
size.
The first one would fit into one page, but the latex.py logic
at Sphinx auto-switches to longtable when there are more than 30
rows. There's no way to override without coding.
The second one is really big, and won't fit on a single page.
So, it has to use tiny font to fit.

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.

Sphinx is really pedantic with respect to the order where
table tags and references are created. Putting things at
the wrong order causes troubles.
The order that seems to work is:
.. raw:: latex
.. tabularcolumns::
.. _foo_name:
.. cssclass: longtable
.. flat-table::
Reorder the tags to the above order, to avoid troubles, and
fix remaining warnings introduced by media recent patches.
