Hi everybody, Here are 6 patches that add a userspace API to the V4L2 subdevices. The API has been developed to support the media controller and the OMAP3 ISP driver. A few people have shown interest in the subdev userspace API already. As the patches are not dependent on the media controller itself I'm submitting them independently for review. The API covers controls, events and generic ioctls. The controls and events support reuse V4L2 ioctls, as explained in Documentation/video4linux/v4l2-framework.txt. The subdev (and later media controller) userspace API should probably be converted to DocBook format eventually. The subdev API can be included in the V4L2 API document, but the media controller should be kept separate. Comments on this will be appreciated. While waiting for review I'll prepare the media controller core patches and send them to the list.
