You can look at sys/dev/pci/puc.c, which is one of the simplest drivers.
PUCs are devices with one or more serial or parallel ports on it, usually
using standar chips (e.g. 16550 UART for serial).
This driver just locate the I/O adresses of the registers of the serial or
parallel controller and passes it to the serial or parallel driver.
