Please start by reading Documentation/PCI/pci.txt and MSI-HOWTO.txt
Lots more useful info in Documentation/ that should help you out
(e.g. suspend/resume, hotplug, DMA API, etc)

Here are some specific driver examples:
    drivers/net/forcedeth.c
    drivers/net/e1000e/
    drivers/scsi/mpt2sas/
    drivers/ata/sata_sil24.c
    drivers/ata/sata_mv.c

hth,
