Hi,

I'm working with an AT91SAM9260 Evaluation Kit and am trying
to make it communicate with an I2C device.  At first I used the 2.6.19
distribution but the driver doesn't seem to detect the peripheral.  The
kernel doesn't call the probe function and so I get the error "No such
device" every time I try to open /dev/i2c-0.  Because of this, I
reverted to 2.6.15.  This time I can open the device but when I try to
read from the device, a Connection Timeout error occurs.  I thought
this was because of the polling issue so I edited it to be interrupt
driven.  I based my changes from the patch posted by Ronny Nilsson.
This, however, didn't solve the problem.  I still get the Connection
Timeout error.  Has anyone used the AT91SAM9260 and encountered a
similar problem? Any advice regarding this issue would be very helpful.

Thanks,
-aldrin-
