I'm a bit surprised it didn't work. I dig just a bit, and found that : - in soc_camera_init_i2c(), the following call fails subdev = v4l2_i2c_new_subdev_board(&ici->v4l2_dev, adap, icl->module_name, icl->board_info, NULL); I have subdev = NULL. - as a result, I'm getting that kind of log : camera 0-0: Probing 0-0 pxa27x-camera pxa27x-camera.0: Registered platform device at c3010900 data c03f0c24 pxa27x-camera pxa27x-camera.0: PXA Camera driver attached to camera 0 RJK: subdev=NULL, module=mt9m111 pxa27x-camera pxa27x-camera.0: PXA Camera driver detached from camera 0 camera: probe of 0-0 failed with error -12 - if I try 2.6.34, I have no error report, and mt9m111 driver is not probed either. Is there an explanation as to why I have this regression ? Is something to be done with the v4l2 migration ? Cheers. -- Robert
