I don't see a lot of added value in doing things this way. We can simply
have a set of new ioctls on the /dev/video# node for this and a new
V4L2_CAP_STILL_IMAGE to indicate the availability of these ioctls. This will keep
the driver a lot simpler then doing 2 separate device nodes for 1 device.

Regards,

Hans
