We keep an alias to avoid breaking userspace applications. Since this alias is only available if __KERNEL__ is *not* defined (i.e. it is only available for userspace, not kernelspace), any drivers that use it also have to be converted to the new define.

media: media.h: reorganize header to make it easier to understand 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 It also contains confusing comment that are either out of date or completely uninteresting for anyone that needs to use this header.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 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] media-device: map new functions into old types for legacy API The legacy media controller userspace API exposes entity types that carry both type and function information. The new API replaces the type with a function. It preserves backward compatibility by defining legacy functions for the existing types and using them in drivers. This works fine, as long as newer entity functions won't be added. Unfortunately, some tools, like media-ctl with --print-dot argument rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE numeric ranges to identify what entities will be shown. Also, if the entity doesn't match those ranges, it will ignore the major/minor information on devnodes, and won't be getting the devnode name via udev or sysfs. As we're now adding devices outside the old range, the legacy ioctl needs to map the new entity functions into a type at the old range, or otherwise we'll have a regression. Detected on all released media-ctl versions (e. g. versions <= 1.10). Fix this by deriving the type from the function to emulate the legacy API if the function isn't in the legacy functions range.

[media] media.h: add support for IF-PLL video/sound decoder Very old hardware may have an analog stage tuner. Those hardware consists of a PLL that converts a RF signal into IF signals. Depending on the hardware, those video IF signal can be decoded directly by the bridge chipset. Most Conexant chips (bt8x8, cx2388x, etc) have internally the decoders for that. Yet, even on such hardware, the tuner may have internally its own TV multi-standard decoder like tda9887. The same happens with the audio IF signal, where some bridges are capable of receiving it, while others require an external IF-PLL sound decoder, like msp3400. Those external IF-PLL audio and video decoders have their own I2C address, and use different drivers to handle them. So, they're mapped as different subdevices on Linux. Thankfully, all modern hardware comes with an IC chip that has both the RF and the IF stages on it, being capable of decoding audio and video IF signals internally. Yet, as we need to support drivers that can work with either analog or silicon tuners, we need to add two entity types for those old hardware.

[media] uapi/media.h: Use u32 for the number of graph objects While we need to keep a u64 alignment to avoid compat32 issues, having the number of entities/pads/links/interfaces represented by an u64 is incoherent with the ID number, with is an u32. In order to make it coherent, change those quantities to u32. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

[media] media: add macros to check if subdev or V4L2 DMA As we'll be removing entity subtypes from the Kernel, we need to provide a way for drivers and core to check if a given entity is represented by a V4L2 subdev or if it is an V4L2 I/O entity (typically with DMA). Drivers that create entities that don't belong to any defined subdev category should use MEDIA_ENT_T_V4L2_SUBDEV_UNKNOWN.

[media] media.h: mark alsa struct in media_entity_desc as TODO The alsa struct in struct media_entity_desc is now marked as deprecated. However, the alsa struct should remain as it is since it cannot be replaced by a simple major/minor device node description. The alsa struct was designed to be used as an alsa card description so V4L2 drivers could use this to expose the alsa card that they create to carry the captured audio. Such a card is not just a PCM device, but also needs to contain the alsa subdevice information, and it may map to multiple devices, e.g. a PCM and a mixer device, such as the au0828 usb stick creates. This is exactly as intended and this cannot and should not be replaced by a simple major/minor. However, whether this information is in the right form for an ALSA device such that it can handle udev renaming rules as well is another matter. So mark this alsa struct as TODO and document the problems involved. Updated the documentation as well to reflect this and to add the 'major' and 'minor' field documentation. Updated the documentation to clearly state that struct dev is to be used for (sub-)devices that create a single device node. Other devices need their own structure here.

[media] media: Fix DVB devnode representation at media controller The previous provision for DVB media controller support were to define an ID (likely meaning the adapter number) for the DVB devnodes. This is just plain wrong. Just like V4L, DVB devices (and any other device node)) are uniquely identified via a (major, minor) tuple. This is enough to uniquely identify a devnode, no matter what API it implements. So, before we go too far, let's mark the old v4l, fb, dvb and alsa "devnode" info as deprecated, and just call it as "dev". We can latter add fields specific to each API if needed. As we don't want to break compilation on already existing apps, let's just keep the old definitions as-is, adding a note that those are deprecated at media-entity.h.
