[media] msi3101: few improvements for RF tuner

2013-08-20T19:09:04+00:00

* Fix AM_MODE. Now it could work at least in theory, cannot test.
* Use greatest common divisor algo to divide PLL fractional parts.
* Fix IF frequency mode.
* + some very minor "style" issues

[media] msi3101: change stream format 384

2013-08-20T19:08:47+00:00

After feeding different signal levels using RF generator and looking
GNU Radio FFT sink I made decision to change bit shift 3 to bit shift
2 as there was very (too) huge visible leap in FFT sink GUI. Now it
looks more natural.

[media] msi3101: implement stream format 504

2013-08-20T19:08:25+00:00

That stream format carries 504 x I+Q samples per 1024 USB frame.
Sample resolution is 8-bit signed. Default it when sampling rate
is 9Msps or over.

[media] msi3101: a lot of small cleanups

2013-08-20T19:08:11+00:00

Add comments, remove useless code and so. House cleaning party.

[media] msi3101: changes for tuner PLL freq limits

2013-08-20T19:07:54+00:00

I made some tuner freq limit tests against RF signal generator.
Adjust some PLL limits according to these test results.
Here are the results, taken from two different devices.
Ranges are measured RF limits + calculated VCO limits.
Mirics MSi3101 SDR Dongle:
VHF_MODE  52 - 132  1664 - 4224
B3_MODE  103 - 263  1648 - 4208
B45_MODE 413 - 960  1652 - 3840
Hauppauge WinTV 133559 LF:
VHF_MODE  49 - 130  1568 - 4160
B3_MODE   98 - 259  1568 - 4144
B45_MODE 391 - 960  1564 - 3840

[media] msi3101: add stream format 336 I+Q pairs per frame

2013-08-20T19:07:29+00:00

That one seem to have 12-bit resolution. Use it for streams that
has sampling rate 6 <= rate (Msps) < 8, between 6 and 8Msps.
