Well.. my copy of drivers/gpio/gpio-pch.c has this near line 440:

static const struct pci_device_id pch_gpio_pcidev_id[] = {
        { PCI_DEVICE(PCI_VENDOR_ID_INTEL, 0x8803) },
        { PCI_DEVICE(PCI_VENDOR_ID_ROHM, 0x8014) },
        { PCI_DEVICE(PCI_VENDOR_ID_ROHM, 0x8043) },
        { PCI_DEVICE(PCI_VENDOR_ID_ROHM, 0x8803) },
        { 0, }
};
MODULE_DEVICE_TABLE(pci, pch_gpio_pcidev_id);

Though I'm having a hard time aligning that with "D31:F2". Are you confusing
a PCI address with a PCI ID, or is this on a non-PCI bus?
