Originally, at the DocBook, the "Byte Order" were a single
paragraph with the string that follows it. The conversion
broke it, and, sometimes, it added an extra dot.
doc-rst: linux_tv: promote generic documents to the parent dir
The generic error codes and licensing sections are general to the
entire media book. They should not be inside the v4l dir. So,
promote them to the parent directory.
Using auto-generated links is dangerous, as there are multiple
definitions for syscalls (at least one on each book part).
So, reference them by their explicit reference.
I used this small script to help writing this patch:
for i in $(git grep -l "c:func:"); do perl -ne 's/\:c\:func:\`(open|close|read|poll|write|select|mmap|munmap|ioctl)\(\)`/:ref:`$1() <func-$1>`/; print $_' < $i >a && mv a $i; done
The conversion script added some comments at the end.
They point to the original DocBook files, with will be
removed after the manual fixes. So, they'll be pointing
to nowere. So, remove those comments.
They'll be forever stored at the Kernel tree. So, if
someone wants the references, it is just a matter of
looking at the backlog.
Fix those warnings:
Documentation/linux_tv/media/v4l/open:38: WARNING: Literal block ends without a blank line; unexpected unindent.
Documentation/linux_tv/media/v4l/open:45: WARNING: Literal block ends without a blank line; unexpected unindent.
The asterisks cause parsing warnings with Sphinx:
Documentation/linux_tv/media/dvb/fe_property_parameters:954: WARNING: Inline substitution_reference start-string without end-string.
/devel/v4l/patchwork/Documentation/linux_tv/media/dvb/fe_property_parameters:993: WARNING: Inline emphasis start-string without end-string.
On the first warning, the ISDB-T layer enabled description is a
kind of ackward. Improve it.
For the second one, IMHO, it is clearer to use [A-C], as it
shows what are the real possibilities, than using asterisk.
The conversion didn't add blank lines where needed, but it
added were it weren't ;)
Fix it, to make it to parse correctly by Sphinx. This also
fixes a bunch or warnings:

WARNING: undefined label: pixfmt-srggb10 (if the link has no caption the label must precede a section heade$
On several places, instead of using references, the code was
using some other tag. Not sure if this was due to the conversion,
or if something were already wrong on the DocBook. In any case,
let's fix them.
All error codes should be const. Most are, but there are
lots of places where we forgot to add <constant> at the DocBook.
Fix those via this small script:
for i in $(git grep -lE "\s+E[A-Z]+\b" Documentation/linux_tv/); do perl -ne 's,([^\`])\b(E[A-Z]+)\b,\1``\2``,g; print $_' <$i >a && mv a $i; done
As there are false positives, we needed to merge only the changes
that make sense, skipping the c blocks and skipping things like
EDID, EN, ETS that were also converted by the above code.
doc-rst: linux_tv: use Example x.y. instead of a single number
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.
doc-rst: planar-apis: fix some conversion troubles
There is a missing escape caracter, causing troubles at the
format of one of the paragraphs. Also, the ioctl description
was producing some warnings about wrong identation.
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.
doc-rst: vidioc-queryctl: change the title of this chapter
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.
This auto-generated file is bogus: it just adds a toc for two
other files. Instead, just move the controls and extended-controls
directly to the common file.
this avoids a blank page, and better organize the document.
As VIDIOC_G_foo is the reference used for VIDIOC_S_foo and
VIDIOC_TRY_foo, we need to explicitly name the reference, as
otherwise, it will mention the three ioctls altogether, with
is not what we want.
doc-rst: linux_tv: Replace reference names to match ioctls
Due to a limitation at the DocBook language, the references
were using lowercase and slashes, instead of the name of the
ioctls. On ReST, make them identical. This will hopefully
help to cleanup the code a little bit.
The Video4Linux documentation is big. We want to numerate the
items, as it makes easier to reference an item while discussing
the document on meetings.

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]

[media] v4l: mt9v032: Do not unset master_mode
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.

[media] tw686x: audio: Prevent hw param changes while busy
Audio hw params are shared across all DMA channels,
so if the user changes any of these while any DMA channel is

serious instability issues.
This commit avoids such situation, by preventing any hw param
change (on any DMA channel) if any other DMA audio channel is capturing.

[media] tw686x: audio: Allow to configure the period size
Currently, the driver has a fixed period size of 4096 bytes
(2048 frames). Since this hardware can configure the audio
capture size, this commit allows a period size range of [512-4096].
Now that we've introduced the dma_mode parameter to pick the
DMA operation, let's use it to also select the audio DMA
operation.
When dma_mode != memcpy, the driver will avoid using memcpy
in the audio capture path, and the DMA hardware operation
will act directly on the ALSA buffers.
