[U-Boot] [PATCH 00/10] 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.


Simon Glass (10):
  x86: Return -1 when reading a PCI config register fails
  x86: minnowmax: Add access to GPIOs E0, E1, E2
  dm: pci: Allow a PCI bus to be found without an alias
  dm: pci: Add a comment to help find pci_hose_read_config_byte, etc.
  x86: minnowmax: Correct pad-offset value for host_en1
  gpio: Report errors when GPIOs cannot be read
  x86: gpio: Correct calls to _ich6_gpio_set_direction()
  x86: gpio: Tidy up gpio_ich6_get_base() and callers
  WIP: x86: gpio: Handle the case where reading a GPIO fails
  WIP: x86: gpio: Make sure that output GPIOs can be read
