The ICH GPIO driver does not work correctly at present. This series tidies things up and fixes a few bugs.
One issue remaining is that reading from output GPIOs does not work - it always returns 0.
Changes in v3: - Correct failure logic in pci_get_bus() - Use pci_get_bus in pci_bus_to_hose()
Changes in v2: - Adjust pci_get_bus() to probe bus 0 so that the required bus is found
