Hi,

I'm trying to launch mx1_camera based on new v4l and soc-camera tree. After loading mx1_camera module, I see that .add callback is not called. In debug log I see that soc_camera_open() is not called too. What should call this function? Is this my driver problem? p.s. loading sensor driver does not change situation.

actually I thought about soc_camera_probe(), not soc_camera_open(). But the problem still the same. video_probe in my driver is not called.

Are you by any chance using last 2.6.29 kernel ?
If so, would [1] be the answer to your question ?

thanks. it means we should expect soc-camera fix for this? I'm using 2.6.29-git8, but seems it's not fixed yet.

No, I don't think so.

The last time I checked there had to be an amendement to the patch which introduced the driver core regression, as it touches other areas as well (sound/soc and mtd from memory).

I think Guennadi can confirm this, as he's the one who raised the issue in the first place.

Cheers.

If Darius had followed the thread you referred to he would have come down to this message

http://lkml.org/lkml/2009/3/26/202

which provides a reply as to "what should be fixed," and yes, Ming Lei has already provided a patch to fix this, it should hit mainstream... some time before -rc1.

Thanks
