[U-Boot] [PATCH v3 0/4] x86: gpio: Tidy up GPIO driver

[Simon Glass]

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

Simon Glass (4):
  dm: pci: Allow a PCI bus to be found without an alias
  gpio: Report errors when GPIOs cannot be read
  WIP: x86: gpio: Handle the case where reading a GPIO fails
  WIP: x86: gpio: Make sure that output GPIOs can be read
