I think the non-8250 serial port platform device numbers will need to be
changed away from TTY_MAJOR.

I ran into this problem on my Amiga 1200. I can't have both the internal
serial port and a PCMCIA modem or COM port currently, because the major
device numbers clash.

Documentation/devices.txt also states about major 4, minor 64 and up
that these are "UART serial ports" and that "UART serial ports refer to
8250/16450/16550 series devices".

This is of course an incompatible change for user land, but IMO it
should be done.


Kind regards,

Kars.
