There are three things: - V4L2 file handles (and events) - V4L2 subdev device nodes - Media controller The file handles and events appear to be fairly ready. > I'd like to implement specific "technician controls", something an > average user wouldn't use, for a few subdevs. For that you'd need at least V4L2 subdev device nodes, preferrably also Media controller e.g. for the user space to know the two devices indeed are connected to the same higher level device. File handles do not matter here; it's just a generic way to store file handle specific data, required by events, for example. Subdev device nodes and Media controller patches live in Laurent's tree at linuxtv.org at the moment.
