Drop the 'experimental' annotations. The only remaining part of the API that is still marked 'experimental' are the debug ioctls/structs, and that is intentional. Only the v4l2-dbg application should use those. All others have been around for years, so it is time to drop the 'experimental' designation.

The DV_TIMINGS_CAP documentation didn't state clearly that the pad and reserved fields should be zeroed by the application. For subdev pad can be other values as well. It also mistakenly said that only drivers would have to zero the reserved field, that's not correct.

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.

During the Seoul media workshop we decided to relax the VIDIOC_CREATE_BUFS specification so it would no longer require drivers to validate the format field since almost no driver did that anyway. Instead drivers use the buffer size(s) based on the format type and the corresponding format fields and will ignore any other fields. If the size cannot be used an error is returned, otherwise the size is used as-is.

It is possible to use: make DOCBOOKS=device-drivers.xml htmldocs To produce just a few docbooks. In such case, the media docs won't be built, causing the makefile target to return an error. While this is ok for human eyes, if the above is used on an script, it would cause troubles. Fix it by only creating/filling the media_api directory if the media_api.xml is found at DOCBOOKS.
