Subject: Serial: sc26xx device name
Date: Sat, 21 Nov 2009 14:51:36 +0100 [thread overview]
Message-ID: <4B07F068.1090801@gmail.com> (raw)
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
