Image captured from MPX-885

Hello

There is "initial" support for the MPX-885 mini-pcie card, see here:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=2cb9ccd4612907c0a30de9be1c694672e0cd8933

Testing an MPX-885 card on an Ubuntu 12.04 amd64 system with kernel 3.2.0.32 the driver in general works with the card. There are some problems, though:

1.) MINOR PROBLEM: The card is not auto-recognized. The module needs to be loaded with the option "card=32" to get it recognized.
2.) MINOR PROBLEM: With PAL camera, there is a black left border of about 20-30 pixel. No border on the right side.
3.) MAJOR PROBLEM: The image is mainly black & white only with some green and red information. There are vertical light green and red stripes

I have attached an image captured with the card. The cable in the background should be pure red. The box in the foreground has a green top. I hope we can fix this, so the card would get usable.

Here is the syslog from loading the module WITHOUT the card=32 option:
