Merge tag 'integrator-pci-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/soc

From Linus Walleij:

This is a patch series that:
- Pulls the Integrator/AP PCI bridge driver into one file
- Adds full device tree support for it
- Keeps ATAG support around for the time being

* tag 'integrator-pci-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator:
  ARM: integrator: basic PCIv3 device tree support
  ARM: integrator: move static ioremapping into PCIv3 driver
  ARM: integrator: move VGA base assignment
  ARM: integrator: remap PCIv3 base dynamically
  ARM: integrator: move V3 register definitions into driver
  ARM: integrator: move PCI base address grab to probe
  ARM: integrator: grab PCI error IRQ in probe()
  ARM: integrator: convert PCIv3 bridge to platform device
  ARM: integrator: merge PCIv3 driver into one file
  ARM: pci: create pci_common_init_dev()
  Documentation/devicetree: add a small note on PCI
