media: lirc_zilog: Don't use dynamic static allocation

2013-12-04T19:06:33+00:00

commit ac5b4b6bf0c84c48d7e2e3fce22e35b04282ba76 upstream.

Dynamic static allocation is evil, as Kernel stack is too low, and
ompilation complains about it on some archs:
	drivers/staging/media/lirc/lirc_zilog.c:967:1: warning: 'read' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer to be 64. That should
be more than enough.

[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: 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
