Subject: Soc-camera and 2.6.33
Date: Mon, 31 May 2010 22:24:06 +0200	[thread overview]
Message-ID: <87fx17vmzd.fsf@free.fr> (raw)


I tried to upgrade from 2.6.30 to 2.6.33 and verify my board (ie. the mt9m111
sensor with pxa_camera host).

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.
