Hi Javier,

I'm testing your patch on a 2.6.39 kernel. Here's what I get when loading the
omap3-isp module.

root@arago:~# modprobe omap3-isp

Have you (or anyone else) seen that issue ?

I build in both statically to avoid that problem.

I used modules and it worked for me.

Thanks

Maybe u-boot version Laurent uses does not enable internal pull-up
resistors for i2c2 interface.
You could either use a different u-boot version or attach external
pull-up resistors to that interface.

The above MLO and uboot enable the pullups and work will all released versions of the beagleboard.

Hi Koen,

So, how is it going?

Are you finally accepting the patches for mainline?

Thank you,

Laurent,
have you been able to successfully test the driver?

I've found some issues and I don't know whether I should send a new
version or just wait for you to mainline the last one and send a patch
later.
