This reverts 'commit 7e0739cd9c40 ("[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.Fixes: 7e0739cd9c40 ("[media] videodev2.h: fix sYCC/AdobeYCC default quantization range")

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.Signed-off-by: Sean Young

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.

The PDF files that contain media images were actually generated
offline from their SVG or PNG source files.Sphinx can handle PNG sources automatially. So, let's just
drop their PDF counterparts.For SVG, however, Sphinx doesn't produce the right tags to
use the TexLive SVG support. Also, the SVG support is done via
shell execution, with is not nice.So, while we don't have any support for SVG inside Sphinx
core or as an extension, move the logic to build them to Makefile,
producing the PDF images on runtime.NOTE: due to the way Sphinx works, the PDF images should be
generated inside the Kernel source tree, as otherwise Sphinx
won't find it, not obeying what's specified by "O=" makefile
parameter.Signed-off-by: Mauro Carvalho Chehab

LaTeX preamble and bind it to just the Sphinx versions where the
