Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This prevents abuse from both userspace and kernelspace (some bridge drivers abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this ioctl). Signed-off-by:

The get_rf_strength op in tuner-simple is valid only for the radio mode. But due to the way get_signal in analog_demod_ops was designed it would overwrite the signal value with a bogus value when in TV mode. Pass a pointer to the signal value instead, and when not in radio mode leave it alone in the tuner-simple. This broke in commit 030755bd (tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before that this was working correctly. That commit did the right thing, but what wasn't realized at the time was that tuner-simple should have been updated as well to restrict setting the signal strength to the radio mode only.

The get_afc op in tda9887 is valid only for the radio mode. But due to the way get_afc in analog_demod_ops was designed it would overwrite the afc value with a bogus value when in TV mode. Pass a pointer to the afc value instead, and when not in radio mode leave it alone in the tda9887. This broke a long time ago in 2.6.19 when the get_afc op was introduced. Before that the afc was only set for radio mode in the tda9887. Signed-off-by:

Make the sensor subdevs host_data hold a pointer to struct fimc_source_info, which is defined in the driver's public header, rather than a pointer to struct fimc_sensor_info which is specific to exynos4-is media device driver. The purpose of this change is to allow easier reuse of the fimc-lite module in the exynos5-is driver, which should similarly store a pointer to struct fimc_source_info instance in the sensor's subdev host_data.

Symbol rate ratio were using a rough calculus, as the code was limited to 32 bits arithmetic. Change it to 64 bits, in order to better estimate the bandwidth low-pass filter on the demod. This should reduce the noise and improve reception. Reported-by:

Using 'i' for the guard interval temporary var is a bad idea, as 'i' is generally used by "anonymous" indexes. Let's rename modulation, fec and guard interval temp vars with a meaningful name, as that makes easier to understand the code and avoids cut-and-paste types of error. Signed-off-by:

config looks like a hack that was added to tuner-core to allow some configuration of TDA8290 tuner (it's not used by any other driver). But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this). Signed-off-by:

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal polarisation. According with the info provided at the BZ, model 92002 does. The difference is that, on model 92001, the tone select is done via isl6421, while, on other devices, this is done via cx24123 code. This patch adds a way to override the demod's set_tone at isl6421 driver. In order to avoid regressions, the override is enabled only for cx88 Nova S plus model 92001. For all other models and devices, the set_tone is provided by the demod driver. Patch originally proposed at bz@9476[1] by Michel Meyers and John Donoghue but applying the original patch would break support for all other devices based on isl6421.
