V4L/DVB (7366): Support for a 16-channel bt878 card
I have what looks like a Geovision GV-600 (or 650) card. It has a large
chip in the middle labeled
CONEXANT
FUSION 878A
25878-13
E345881.1
0312 TAIWAN
It has an audio connector coming out from a chip labeled
ATMEL
0242
AT89C2051-24PI
It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18)

It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18
kernel and the latest v4l-dvb drivers, but it did not work at all. The
card has sixteen (16) BNC video inputs, four of them on the board itself
and twelve on three daughter-cards. It has a single bt878 chip, no tuner
and what looks like and audio input. After doing some research I managed
to get only eight channels working by forcing card=125 and those DID NOT
match channels 0-7 on the card, and no audio.
Based on what was working for card=125, I added the card definition
block, added a specific muxsel routine and got the card working fully
with xawtv, where the sixteen channels show up as Composite0 to
Composite15, matching the channel labels in the card and daughter-cards.
I have made no efforts yet to get audio working, but would appreciate
any pointers.
