2014-03-14[media] e4000: convert to Regmap APIAntti Palosaari3-147/+68
That comes possible after driver was converted to kernel I2C model (I2C binding & proper I2C client with no gate control hack). All nasty low level I2C routines are now covered by regmap.

2014-03-14[media] rtl2832_sdr: Realtek RTL2832 SDR driver moduleAntti Palosaari6-0/+1542
Implement SDR driver for Realtek RTL2832U chip as a DVB extension module. SDR module is attached by DVB USB RTL28XXU driver as a DVB SEC (satellite equipment controller) module. Abusing unused SEC here has no harm as that is DVB-T only frontend. SDR functionality is provided by RTL2832 DVB-T demodulator. I suspect it is originally planned for DAB and FM, but it could be abused general SDR, due to modern silicon tuners that has wide frequency range and a lot of configurable parameters (filters, gains, ...). http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/44461 Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

It appears that controls are ordered by ID number when enumerating. That could lead illogical UI as controls are usually enumerated and drawn by the application at runtime.

2014-03-13[media] v4l: add RF tuner channel bandwidth controlAntti Palosaari2-0/+6
Modern silicon RF tuners has one or more adjustable filters on signal path, in order to filter noise from desired radio channel. Add channel bandwidth control to tell the driver which is radio channel width we want receive. Filters could be then adjusted by the driver or hardware, using RF frequency and channel bandwidth as a base of filter calculations. On automatic mode (normal mode), bandwidth is calculated from sampling rate or tuning info got from userspace. That new control gives possibility to set manual mode and let user have more control for filters.
