PCI is a bus. And something like SSB is a bus. There is a protocol, there's device with identity on the bus, there's stuff going on. The SBBI driver has neither addresses nor a protocol. It's literally just an embedded on-chip serial device as far as I can tell. There's nothing "bus" about it. It's just a hose. Yeah, yeah, at some point you can call "anything" a bus. I could call my little two-seater car a "school bus", because it has wheels, it's even yellow exactly like the school buses around here. And I can put a child in it. So my little yellow two-seater must be a bus too. It's all just how you define your words. But it's a damn big reach. I didn't use to call the serial line connecting my computer to the modem a "bus". Even if it connected two devices.
