Sphinx 1.6 generates some LaTeX code before each table,

apparently to improve table layout.
The problem is that such environment is incompatible with
adjustbox. While, in thesis, it should be possible to override
it or to redefine tabulary, I was unable to produce such patch.
Also, that would likely break on some future Sphinx version.
So, instead, let's just change the font size on bigger tables,

good as adjustbox, and require some manual work, but it should
be less sensitive to Sphinx changes.

"Media updates for v4.12-rc1:

- rc-lirc, s5p-cec and st-cec staging drivers got promoted
- hardware histogram support for vsp1 driver
- added Virtual Media Controller driver, to make easier to test the

- added a new CEC driver (rainshadow-cec)
- removed two staging LIRC drivers for obscure hardware that are too

- added support for Intel SR300 Depth camera
- some improvements at CEC and RC core

Here is the big USB patchset for 4.12-rc1.
Lots of good stuff here, after many many many attempts, the kernel
finally has a working typeC interface, many thanks to the Heikki and
Guenter and others who have taken the time to get this merged. It
wasn't an easy path for them at all.
There's also a staging driver that uses this new api, which is why it's
coming in through this tree.
Along with that, there's the usual huge number of changes for gadget
drivers, xhci, and other stuff. Johan also finally refactored pretty
much every driver that was looking at USB endpoints to do it in a common
way, which will help prevent any "badly-formed" devices from causing
problems in drivers. That too wasn't a simple task.
All of these have been in linux-next for a while with no reported
issues.

Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
V4L2 exposes parameters that influence buffers sizes through the format
ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly
VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of
the format structure may also influence buffer sizes or buffer layout in
general. One existing such parameter is rotation, which is implemented
by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control
ioctls.
The interaction between those parameters and buffers is currently only
partially specified by the V4L2 API. In particular interactions between
controls and buffers isn't specified at all. The behaviour of the
VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is
also not fully specified.
This patch clearly defines and documents the interactions between
formats, selections, controls and buffers.
The preparatory discussions for the documentation change considered
completely disallowing controls that change the buffer size or layout,
in favour of extending the format API with a new ioctl that would bundle
those controls with format information. The idea has been rejected, as
this would essentially be a restricted version of the upcoming request
API that wouldn't bring any additional value.
Another option we have considered was to mandate the use of the request
API to modify controls that influence buffer size or layout. This has
also been rejected on the grounds that requiring the request API to
change rotation even when streaming is stopped would significantly
complicate implementation of drivers and usage of the V4L2 API for
applications.
Applications will however be required to use the upcoming request API to
change at runtime formats or controls that influence the buffer size or
layout, because of the need to synchronize buffers with the formats and
controls. Otherwise there would be no way to interpret the content of a
buffer correctly.

The documentation for video capture and output devices claims that the video standard
ioctls are required. This is not the case, they are only required for PAL/NTSC/SECAM
type inputs and outputs. Sensors do not implement this at all and e.g. HDMI inputs
implement the DV Timings ioctls.
Just drop the mention of 'video standard' ioctls.

The xvYCC601/709 encodings were mapped by default to full range quantization.
This is actually wrong since these encodings use limited range quantization,
but accept values outside of the limited range.
This makes sense since for values within the limited range it behaves exactly
the same as BT.601 or Rec. 709. The only difference is that with the xvYCC
encodings the values outside of the limited range also produce value colors.
Talking to people who know a lot more about this than I do made me realize
that mapping xvYCC to full range quantization was wrong, so this patch corrects
this and also improves the documentation.
These formats are very rare, and since the formula for decoding these Y'CbCr
encodings is actually fixed and independent of the quantization field value
it is safe to make this change.
The main advantage is that keeps the V4L2 specification in sync with the
corresponding colorspace, HDMI and CEA861 standards when it comes to these
xvYCC formats.

This reverts 'commit 7e0739cd9c ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").
The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.
To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.
Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.
In addition, we need to know the specific variant of the protocol.
In short, these changes are made to the wakeup_protocols sysfs entry:
- list all the protocol variants rather than the protocol groups,
e.g. "nec nec-x nec-32" rather than just "nec".
- only allow one protocol variant to be selected rather than multiple
- wakeup_filter can only be set once a protocol has been selected in
wakeup_protocols.
This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.
As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.
Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.
The patch has been generated using the following command:
git grep -l media_entity |xargs perl -i -pe '
s/media_entity_pipeline/media_pipeline/g;
s/media_entity_graph/media_graph/g'
And a few manual edits related to line start alignment and line wrapping.
