Serial: sc26xx device name

[Martin Fuzzey <mfuzzey@gmail.com>]

Hi all,
I noticed the sc26xx driver uses ttySC205 / ttySC206 for device name.

grep ttySC Documentation/devices.txt gives
          8 = /dev/ttySC0        SCI serial port (SuperH) - port 0
          9 = /dev/ttySC1        SCI serial port (SuperH) - port 1
         10 = /dev/ttySC2        SCI serial port (SuperH) - port 2
         11 = /dev/ttySC3        SCI serial port (SuperH) - port 3
         205 = /dev/ttySC0        SC26xx serial port 0
         206 = /dev/ttySC1        SC26xx serial port 1
         207 = /dev/ttySC2        SC26xx serial port 2
         208 = /dev/ttySC3        SC26xx serial port 3
          8 = /dev/cusc0        Callout device for ttySC0
          9 = /dev/cusc1        Callout device for ttySC1
         10 = /dev/cusc2        Callout device for ttySC2
         11 = /dev/cusc3        Callout device for ttySC3

Removing the line:
    sc26xx_reg.tty_driver->name_base = sc26xx_reg.minor;
makes it revert to ttySC0

So two questions:
1) Who is right (the driver or devices.txt)?
2) How are device name conflicts handled?

Cheers,

Martin
