Merge branch 'pci/host-generic' into next
* pci/host-generic:
arm64: Add architectural support for PCI
PCI: Add pci_remap_iospace() to map bus I/O resources
of/pci: Add support for parsing PCI host bridge resources from DT
of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()
PCI: Add generic domain handling
of/pci: Fix the conversion of IO ranges into IO resources
of/pci: Move of_pci_range_to_resource() to of/address.c
ARM: Define PCI_IOBASE as the base of virtual PCI IO space
of/pci: Add pci_register_io_range() and pci_pio_to_address()
asm-generic/io.h: Fix ioport_map() for !CONFIG_GENERIC_IOMAP
