cx88 driver: Help needed to add radio support on Leadtek WINFAST DTV 2000 H (version J)

[Andre Auzi <aauzi@xxxxxxxxxxxxxxxxxxxxx>]

Hello list,

I've started the task to add support of the board mentionned above.

So far I've got analog TV, Composite and Svideo inputs working OK with 
IR as well.

Unfortunately, my area does not have DVB-T yet, but from the scans I've 
made, I'm confident DVB support is on good tracks.

Nevertheless, I cannot achieve to have the radio input working.

The gpio values were captured with regspy on a working windows installation.

Here are my additions in cx88-cards.c:

Would there be someone in the list with cx88 driver knowledge who 
already achieved this for another board and could hint me on things to 
look for?

I kindof reached the limits of my imagination and would really 
appreciate a help.

So far my modprobe.conf reads:

options tda9887 debug=1
options cx22702 debug=1
options cx88xx i2c_debug=1 i2c_scan=1 audio_debug=1
options cx8800 video_debug=1

and I would join the dmesg output if I did not care to flood the list.

Just let me know if it could help.

Thanks in advance
Andre
