Re: Avermedia dvb-t hybrid A188

[Davor Emard <davoremard@gmail.com>]

HI

This is my second attempt on Avermedia A188.
The hardware on this card is:

1x Philips SAA7160 pci-e bridge
2x NXP SAA7136 multistandard 10-bit A/V decoder
2x Afatech AF9013S demodulator
2x NXP TDA18271 silicon tuner ic (digital/analog)

I've written af9013 frontend attach code but I'm having
problems with loading firmware.

If someone can scan the card on window$ and see what the
driver does, are there some gpios that turn on the frontend
would be nice (maybe also extract correct firmware)

What I did
-----------
started from saa716x tree
hg clone http://www.jusst.de/hg/saa716x/
and added the af9013 frontend.

It compiles fine, loads af9013 module and requests
firmware but it won't load

Firmware was downloaded from http://www.otit.fi/~crope/v4l-dvb/af9015/dvb-fe-af9013.fw 
Also tried another firmware for af9015 usb sticks

In the code I made a loop to try i2c addresses from 0x00-0x7f
for af9013 but so far not found the correct one

The patch avermedia-005.diff
