This is just a reminder: please send me one .dot file that you used to create the subdev mapping for one of the devices. The more complex, the better.

As I said, my idea is to write a small rfc file using it as an example, in order to give a clear separation when someone should use udev/sysfs (or some equivalent script on embedded systems) to discover the device topology, and when media controller should be used. We need to have some sort of guidelines for userspace developers, as we will have two ways to get topology, and the reported topology may be different between those two, depending on how userspace is creating the device files at /dev.
