media: videodev2.h: Fix struct v4l2_input tuner index comment

2023-08-11T09:45:12+00:00

[ Upstream commit 26ae58f65e64fa7ba61d64bae752e59e08380c6a ] VIDIOC_ENUMINPUT documentation describes the tuner field of struct v4l2_input as index: Documentation/userspace-api/media/v4l/vidioc-enuminput.rst " * - __u32 - ``tuner`` - Capture devices can have zero or more tuners (RF demodulators). When the ``type`` is set to ``V4L2_INPUT_TYPE_TUNER`` this is an RF connector and this field identifies the tuner. It corresponds to struct :c:type:`v4l2_tuner` field ``index``. For details on tuners see :ref:`tuner`. " Drivers I could find also use the 'tuner' field as an index, e.g.: drivers/media/pci/bt8xx/bttv-driver.c bttv_enum_input() drivers/media/usb/go7007/go7007-v4l2.c vidioc_enum_input() However, the UAPI comment claims this field is 'enum v4l2_tuner_type': include/uapi/linux/videodev2.h This field being 'enum v4l2_tuner_type' is unlikely as it seems to be never used that way in drivers, and documentation confirms it. It seem this comment got in accidentally in the commit which this patch fixes. Fix the UAPI comment to stop confusion. This was pointed out by Dmitry while reviewing VIDIOC_ENUMINPUT support for strace.

[ Upstream commit 8da7f0976b9071b528c545008de9d10cc81883b1 ] If it is a progressive (non-interlaced) format, then ignore the interlaced timing values.

media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:08:40+00:00

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ] The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

media: replace ADOBERGB by OPRGB

2018-11-13T19:08:54+00:00

commit db0340182444612bcadb98bdec22f651aa42266c upstream. The CTA-861 standards have been updated to refer to opRGB instead of AdobeRGB. The official standard is in fact named opRGB, so switch to that. The two old defines referring to ADOBERGB in the public API are put under #ifndef __KERNEL__ and a comment mentions that they are deprecated.
