AF9035/AF9033 development

[Antti Palosaari]

Here is TODO list I took from mail I wrote 31.3.2012:

* fix af9033 IF freq control (now Zero-IF only)
DONE

* change firmware download to use new firmware syntax
DONE

* dual tuner support

* check if IT9035 is enough similar (My personal suspicion is that 
integrated tuner is only main difference, whilst USB-interface and demod 
are same. But someone has told that it is quite different design though.)
DONE. It is similar. AF9035 code changes are done. New tuner driver 
still needed.

* implement SNR, BER and USB counters
partly DONE!

* implement remote controller



Remote controller and dual tuner support are main missing features. I 
will try implement remote controller next, maybe later tonight.

Antti

I failed that. After many hours of hacking I did not succeed to disable 
HID. It is very weird since HID outputs some random letters even there 
is no keytable loaded to device and some other than device own NEC 
remote used.
I can read raw key codes from the firmware, but as the HID is still 
there it is useless. I even tried to load some garbage key tables to 
kill HID - but no success. So I will give up as now.
I think it is possible to edit eeprom to kill HID, but that kind of 
eeprom modification is no way to go.
