Avermedia dvb-t hybrid A188

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

I'm not sure why, but there are two drivers for saa716x chips, one out of the tree (never submitted upstream), and the otherone that were submited and is already merged at the kernel tree.

The patch you've done is for the other driver. So, I can't apply it. If you want to base it in the top of the driver found at the kernel tree, at drivers/media/video/saa7164/, I can apply it.
