2017-02-23videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGBHans Verkuil
commit 35879ee4769099905fa3bda0b21e73d434e2df6a upstream. 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.

2017-01-12docs-rst: fix LaTeX \DURole renewcommand with Sphinx 1.3+Mauro Carvalho Chehab
commit e2a91f4f42018994d7424d405900d17eba6555d0 upstream. PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x and Sphinx 1.4.x, when trying to solve some cross-references. The solution is to redefine the \DURole macro. However, this is redefined too late. Move such redefinition to LaTeX preamble and bind it to just the Sphinx versions where the error is known to be present.

2016-09-09[media] doc-rst: 16-bit BGGR is always 16 bitsSakari Ailus
The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer than 16 bits. However, we do have specific definitions for smaller sample sizes. Therefore, this note is redundant from the API point of view. Currently only two drivers, am437x and davinci, use the V4L2_PIX_FMT_SBGGR16 pixelformat currently. The sampling precision is understood to be 16 bits in all current cases. Remove the note on sampling precision.

The V4L version 1 structures had long gone from the Linux Kernel. It doesn't make sense to use cross-references for them, as they won't be found. So, get rid of them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] docs-rst: convert uAPI structs to C domainMauro Carvalho Chehab
instead of declaring the uAPI structs using usual refs, e. g.: .. _foo-struct: Use the C domain way: .. c:type:: foo_struct This way, the kAPI documentation can use cross-references to point to the uAPI symbols. That solves about ~100 undefined warnings like: WARNING: c:type reference target not found: foo_struct Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] conf_nitpick.py: ignore external functions used on mediactlMauro Carvalho Chehab
There are some functions/macros used by the mediactl documentation that are alien to the media subsystem. Ignore them. After this patch, the media core will only complain about this static function: Documentation/media/kapi/mc-core.rst:97: WARNING: c:func reference target not found: media_devnode_release Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] mc-core.rst: Fix cross-references to the sourceMauro Carvalho Chehab
The cross-reference to "struct media_pad" was pointing to a place that doesn't exist. Fix it, and adjust the second reference on the same paragraph to use the same text. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] dtv-core.rst: move DTV ringbuffer notes to kAPI docMauro Carvalho Chehab
Instead of keeping those notes at the file on a non-structured way, move them to dtv-core.rst, using the proper ReST tags. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] conf_nitpick.py: add external vars to ignore listMauro Carvalho Chehab
There a some other types and functions that aren't declared inside the media document but are elsewhere. Add them to the ignore list. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
