    [SERIAL] Add new port registration/unregistration functions. · befff6f5
    Russell King authored
    serial8250_register_port()/serial8250_unregister_port() has the
    capability of registering ports with their struct device nodes,
    which allows sysfs to indicate which tty devices belong to which
    hardware devices.
    
    We also add a serial8250 platform device driver in an initial
    attempt at PM for ISA ports.  However, I'm leaving out the
    platform device for the time being since adding that would cause
    potential oops issues.
