media: media.h: reorganize header to make it easier to understand

2018-02-26T15:14:46Z

The media.h public header is very messy. It mixes legacy and 'new' defines and it is not easy to figure out what should and what shouldn't be used. It also contains confusing comment that are either out of date or completely uninteresting for anyone that needs to use this header. The patch groups all entity functions together, including the 'old' defines based on the old range base. The reader just wants to know about the available functions and doesn't care about what range is used. All legacy defines are moved to the end of the header, so it is easier to locate them and just ignore them. The legacy structs in the struct media_entity_desc are put under also a much more effective signal to the reader that they shouldn't be used compared to the old method of relying on '#if 1' followed by a comment. The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header in the legacy area. They are also dropped from intf_type() in media-entity.c. All defines are also aligned at the same tab making the header easier to read.

License cleanup: add SPDX license identifier to uapi header files with a license

2017-11-02T10:20:11Z

Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

media: drop use of MEDIA_API_VERSION

2017-08-08T10:03:15Z

Set media_version to LINUX_VERSION_CODE, just as we did for driver_version. Nobody ever rememebers to update the version number, but LINUX_VERSION_CODE will always be updated. Move the MEDIA_API_VERSION define to the ifndef __KERNEL__ section of the media.h header. That way kernelspace can't accidentally start to use it again.

[media] v4l2-core: Add support for touch devices

2016-08-23T19:28:04Z

Some touch controllers send out touch data in a similar way to a greyscale frame grabber. Add new device type VFL_TYPE_TOUCH: - This uses a new device prefix v4l-touch for these devices, to stop generic capture software from treating them as webcams. Otherwise, touch is treated similarly to video capture. - Add V4L2_INPUT_TYPE_TOUCH - Add MEDIA_INTF_T_V4L_TOUCH - Add V4L2_CAP_TOUCH to indicate device is a touch device Add formats: - V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas - V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas - V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data - V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data This support will be used by: - Atmel maXTouch (atmel_mxt_ts) - Synaptics RMI4. - sur40 Signed-off-by: Nick Dyer Tested-by: Chris Healy Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab Acked-by: Dmitry Torokhov
