I'm a bit confused, what this anybus stuff actually does.

Is it some proprietary backplane bus, where things like eg. fieldbus
adapters are attached to ?

I see some struct bus_type field declaration - is that going to be some
subsystem, similar to those for other bus'es (eg. pci, usb, ...) ?

Maybe that deserves a bit more documentation :p
