[media] TS2020: Calculate tuner gain correctly The TS2020 and TS2022 tuners take an input from the demodulator indicating the AGC setting on that component that is then used to influence the tuner's own gain. This should be taken into account when calculating the gain and signal strength. Further, the existing TS2020 driver miscalculates the signal strength as the result of its calculations can exceed the storage capacity of the 16-bit word used to return it to userspace. To this end: (1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that the tuner can call to get the AGC PWM value from the demodulator. (2) Modify the TS2020 driver to calculate the gain according to Montage's specification with the adjustment that we produce a negative value and scale it to 0.001dB units (which is what the DVBv5 API will require): (a) Callback to the demodulator to retrieve the AGC PWM value and then turn that into Vagc for incorporation in the calculations. If the callback is unset, assume a Vagc of 0. (b) Calculate the tuner gain from a combination of Vagc and the tuner's RF gain and baseband gain settings. (3) Turn this into a percentage signal strength as per Montage's specification for return to userspace with the DVBv3 API. (4) Provide a function in the M88DS3103 demodulator driver that can be used to get the AGC PWM value on behalf of the tuner. (5) The ts2020_config.get_agc_pwm function should be set by the code that stitches together the drivers for each card. For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022, set the get_agc_pwm function to point to m88ds3103_get_agc_pwm. I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022. Thanks to Montage for providing access to information about the workings of these parts.
