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.

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)".

The table is too big to fit into a single page on LaTeX format.
Signed-off-by: NMauro Carvalho Chehab <mchehab@s-opensource.com>

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.

Signed-off-by: NMauro Carvalho Chehab <mchehab@s-opensource.com>

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.
