3 * Support for common PCI multi-I/O cards (which is most of them)
4 *
5 * Copyright (C) 2001 Tim Waugh <twaugh@redhat.com>
6 *
7 * Multi-function PCI cards are supposed to present separate logical
8 * devices on the bus. A common thing to do seems to be to just use
9 * one logical device with lots of base address registers for both
10 * parallel ports and serial ports. This driver is for dealing with
11 * that.
