I had a look at cafe_ccic.c and also at vpif_capture.c.

I tried to use "v4l2_i2c_new_subdev_board", but at boot time I have the 
following error:
i2c i2c-0: Failed to register i2c client ov2640 at 0x30 (-16)


I don't understand where it could come from, I pass the proper 
i2c_board_info struct, and it seems to check the proper i2c address, 
since it is not working.

Basically I do like cafe_ccic.c execpt that I use the 
v4l2_i2c_new_subdev_board instead of v4l2_i2c_new_subdev...

Any idea why I can't detect the sensor here?
