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?
