This is my version 13 of the attempt at adding support for generic PCI host
bridge controllers. It contains only cleanups to make it play nice with the
linux-next tree as of 09/25. If Bjorn deems it safe, now that it looks like
asm-generic is going to revert some of its more aggresive patches, he has the
choice of queueing it into linux-next again.
...

These patches above were already on my pci/host-generic branch and in
linux-next:

   asm-generic/io.h: Fix ioport_map() for !CONFIG_GENERIC_IOMAP

This ^ ...

   of/pci: Add pci_register_io_range() and pci_pio_to_address()
   ARM: Define PCI_IOBASE as the base of virtual PCI IO space

and this ^ need to be refreshed from my series otherwise we will get conflicts with
asm-generic branch (either now or in the future). While the asm-generic/io.h
cast is arguably superflous, we need to define PCI_IOBASE as a void __iomem* to
match all other standard declarations of PCI_IOBASE.

   of/pci: Define of_pci_range_to_resource() only when CONFIG_PCI=y
   of/pci: Move of_pci_range_to_resources() to of/address.c
   of/pci: Fix the conversion of IO ranges into IO resources

I added these three patches to my pci/host-generic branch:

   PCI: Add generic domain handling
   of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()
   of/pci: Add support for parsing PCI host bridge resources from DT

I can see these patches added to pci/host-generic but not on pci/next.

Yinghai pointed out a problem with this one, so I omitted it:

   PCI: Assign unassigned bus resources in pci_scan_root_bus()

Thats fine, host bridge drivers will have to work around pci_scan_root_bus() reduced
functionality for now.

I added this one to my pci/host-generic branch:

   PCI: Add pci_remap_iospace() to map bus I/O resources

I assume this depends on the pci_scan_root_bus() change (if not, let me
know), so I omitted this one:

   arm64: Add architectural support for PCI

No, there is no dependency there on pci_scan_root_bus(), it can go in the series.
The only thing that depends on a feature rich pci_scan_root_bus() is the host
bridge driver in order to be able to use only one line to process the root bus.

Thanks for huge support in getting these patches in and I do hope I'm not being
too much of a burden to you.

Best regards,
Liviu
