Unfortunately my camera is not responding to I2C commands, I already
slow it down to 10kbps with no success. I can see on oscilloscope
i.MX27 send I2C commands, but the camera doesn't respond to it.

Then I tested using the MT9T31 driver and change the it to my I2C
commands, as I2C is failing I force the probe to return 0. But the
soc_camera still failing:

Linux video capture interface: v2.00
write: -5
MT9T31 Read register 0xFF = -5
Forcing mt9t031_video_probe to return OK!
mx27-camera mx27-camera.0: initialising
mx27-camera: probe of mx27-camera.0 failed with error -2

Best Regards,

Alan
