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. It is being worked on: http://www.spinics.net/lists/linux-media/msg34878.html and, hopefully, beginning with the next kernel version 3.1 it will become at least theoretically possible. For now you just have to hack the driver yourself for your local uses by removing all soc-camera specific code and replacing it with your own glue, something along these lines: http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/11486/focus=11691 Thanks Guennadi --- Guennadi Liakhovetski, Ph.D. Freelance Open-Source Software Developer http://www.open-technology.de/ -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
