But in the linux kernel 2.6.38,the driver of the mt9m111 is a soc_camera.I see some thing about how to convert the soc_camera to V4L2,like "soc-camera: (partially) convert to v4l2-(sub)dev API". > > Can you tell me how to migrate from soc_camera to v4l2,and > > or do you tell me some experience about that? > > Currently there's no standard way to make a driver to work with both > soc-camera and (pure) v4l2-subdev APIs.

I have not taken a deeper look at it yet. But what do you mean by theoretically possible? Could it work out of the box? Or is there more work to do?
