Am I reading this series correct in that this is the only "user" of the
new ancilicary bus/driver code?

If so, why is it even needed?  These are just debugfs files for testing,
why does that need to be in a separate device?  What is being "shared"
here that needs multiple struct devices to handle?

confused,
