No but it can provide information to help user space. In many cases the decision isn't about a line discipline but about automatically setting permissions or linking ports to the right driver. The hints need to be generic - they can come from open firmware, from pci identifiers, from ACPI and so on. > Shall we change the uart_bus to the tty_bus, then introduce tty_host / tty_target for the bus? We have a tty class - is that not sufficient ?
