What about the fact that it's an Open Firmware driver?  My driver gets probed
for each byte channel node in the device tree.

I'm still not sure why you think I have a bus.  I don't see where the UART
drivers register a bus, and there's not a whole lot different between a byte
channel and a UART.

I never said we have a bus.  There is no entity that conglomerates the byte
channels.
