2015-10-20[media] v4l2: add RF gain controlAntti Palosaari
Add new RF tuner gain control named RF Gain. That is aimed for first amplifier chip right after antenna connector. There is existing LNA Gain control, which is quite same, but it is aimed for cases amplifier is integrated to tuner chip. Some designs have both, as almost all recent tuner silicons has integrated LNA/RF amplifier in any case.

2015-10-20[media] v4l2: rename V4L2_TUNER_ADC to V4L2_TUNER_SDRAntti Palosaari
SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter has DAC (Digital-to-Analog Converter). Originally I though it could be good idea to have own type for receiver and transmitter, but now I feel one common type for SDR is enough. So lets rename it.

2015-10-20[media] smiapp: Export OF module alias informationJavier Martinez Canillas
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

The second one is used only on the obsolete av7110 driver, and its purpose is not clear, as it just returns a 64-bit word from the firmware to userspace.

2015-10-06[media] DocBook: Move struct dmx_demux kABI doc to demux.hMauro Carvalho Chehab
The DocBook/media/dvb/kdapi.xml contains the description of the kABI for DVB. The problem is that, by being maintained on a separate file and not being updated for years, it got outdated. So, for example, some callback parameters were changed, but the DocBook were still using the old stuff. As a first step to fix it, let's move the documentation of struct dmx_demux into demux.h and fix the parameters used there. For now, don't document any other field nor touch the descriptions that got moved, letting this job to other patches. That makes easier to review the patch. PS.: Please notice that an additional patch will be needed in order to fix the return values (some uses non-existent return codes) and to the functions and callbacks mentioned at the descriptions.
