[linux-dvb] Terratec Cinergy S PCI

Hi List.

I recently bought a Terratec Cinergy S PCI which uses a Conexant CX2388x 
chip as it's PCI Interface and a Fujitsu MB86A16 as it's frontend.

I modified the cx88 files to recognize this card. Now I need a some 
pointers how to attach the MB86A16 frontend (which is included in mantis 
source, i think) to the cx88 and how to obtain the right i2c adresses etc.

Is there any documentation on how to do that?
I would be very happy to contribute to the great work you do and already 
did.
