[PATCH] [SERIAL] add TP560 data/fax/modem support

From: Bjorn Helgaas
Date: Mon Feb 07 2005 - 15:05:20 EST


Claim Topic TP560 data/fax/voice modem. This device reports as class 0x0780,
so we don't claim it by default:

00:0d.0 Class 0780: 151f:0000
Subsystem: 151f:0000
Interrupt: pin A routed to IRQ 11
Region 0: I/O ports at a400 [size=8]
00: 1f 15 00 00 01 00 00 02 00 00 80 07 00 00 00 00
10: 01 a4 00 00 00 00 00 00 00 00 00 00 00 00 00 00
20: 00 00 00 00 00 00 00 00 00 00 00 00 1f 15 00 00
30: 00 00 00 00 00 00 00 00 00 00 00 00 0b 01 00 00

Some rc.serial scripts extract IRQ and I/O port information from
/proc/pci and stuff it into an unused port using setserial. That
doesn't work reliably anymore because pci_enable_device() is never
called, so the IRQ may not be enabled.

Thanks to Evan Clarke for reporting and helping debug this problem.
