On the example captions, use always <chapter>.<number>., because:
1) it matches the DocBook;
2) it would mean less changes if we need to add a new example,
as only one chapter will be affected.

The conversion on this file didn't end too well. fix the found
issues:
1) Sphinix seems to not allow things like *foo :ref:`bar`*. At least
on this document, it did the wrong thing. So, change the logic to
something that will work fine with ReST format;
2) Some ioctl pointers were not looking nice;
3) the captions on the examples got discarded;
4) The notes specific to each example were not converted well.
Again, we'll need to replace it for a simpler design, as Sphinx
is a way more limited than DocBook.

The c language parser checks if there are duplicated object
definitions. That causes lots of warnings like:
WARNING: duplicate C object description of ioctl
Let's remove those by telling Sphinx that the language for
those objects are c++. The look of the descriptions will
be close, and the warnings will be gone.
Please notice that we had to keep a few of them as C, as
the c++ parser seems to be broken when it finds an enum.
Yet, this reduced from 219 warnings to 143, with is
a good thing.

This chapter is referenced on several parts of the extended
controls. Change the title to make it nicer where it is
referenced.
Ok, we might, instead, just change the name for the references
to only mention the oldest ioctl, but IMHO, it is better to
keep the name of all ioctls where it is referenced.

Implements the reST flat-table directive.
The ``flat-table`` is a double-stage list similar to the ``list-table`` with
some additional features:
* column-span: with the role ``cspan`` a cell can be extended through
additional columns
* row-span: with the role ``rspan`` a cell can be extended through
additional rows
* auto span rightmost cell of a table row over the missing cells on the right
side of that table-row. With Option ``:fill-cells:`` this behavior can
changed from *auto span* to *auto fill*, which automaticly inserts (empty)
list tables
The *list tables* formats are double stage lists. Compared to the
ASCII-art they migth be less comfortable for readers of the
text-files. Their advantage is, that they are easy to create/modify
and that the diff of a modification is much more meaningfull, because
it is limited to the modified content.
The initial implementation was taken from the sphkerneldoc project [1]

The power_on function of the driver resets the chip and sets the
CHIP_CONTROL register to 0. This switches the operating mode to slave.
The s_stream function sets the correct mode. But this caused problems on
a board where the camera chip is operated as master. The camera started
after a random amount of time streaming an image, I observed between 10
and 300 seconds.
The STRFM_OUT and STLN_OUT pins are not connected on this board which
may cause some issues in slave mode. I could not find any documentation
about this.
Keeping the chip in master mode after the reset helped to fix this
issue for me.
