Subject: [PATCH 00/10] PCI: Add generic Conf Type 0/1 helpers

This series replaces PCI_CONF1{,_EXT}_ADDRESS() with more generic
helpers and makes them more widely available by placing the new helpers
into include/linux/pci.h.

Most of what is under drivers/pci/controller is converted to use the
new helpers by this series. I left arch/ changes out from this because
they're quite varied so they would be harder to verify (and review)
except ARM/orion5x that I had to do now due to a naming conflict.
Nonetheless, there is plenty custom type 0/1 code under arch/ that
could now take advantage of the new helpers.

I've postponed touching pcie-mediatek.c because there's odd slot
calculation which I brought up in another thread.

Ilpo Järvinen (10):
  ARM: orion5x: Rename PCI_CONF_{REG,FUNC}() out of the way
  PCI: Add helpers to calculate PCI Conf Type 0/1 addresses
  ARM: orion5x: Pass devfn to orion5x_pci_hw_{rd,wr}_conf()
  ARM: orion5x: Use generic PCI Conf Type 1 helper
  PCI: ixp4xx: Use generic PCI Conf Type 0 helper
  PCI: ixp4xx: Replace 1 with PCI_CONF1_TRANSACTION
  PCI: Replace PCI_CONF1{,_EXT}_ADDRESS() with the new helpers
  PCI: tegra: Use generic PCI Conf Type 1 helper
  PCI: mvebu: Use generic PCI Conf Type 1 helper
  PCI: v3: Use generic PCI Conf Type 0/1 helpers
