Subject: [PATCH v7 0/4] pci: iproc: Add Broadcom iProc PCIe support

This patch series adds the support for Broadcom iProc PCIe controller

pcie-iproc.c servers as the common core driver, and front-end bus
interface needs to be added to support different bus interfaces

pcie-iproc-pltfm.c contains the support for the platform bus interface

Changes from v6:
 - Fix print formatting
 - Fix section mismatch warning by removing __init from the probe function
 - Fix Kconfig to force it only compiling for ARM based platforms

Changes from v5:
 - Sync code base to v4.0-rc2
 - Change export symbols of common PCI functions to GPL only
 - Add comment to describe how configuration register access are protected
   at the higher layer through 'pci_lock'
 - Use generic PCI functions for configuration register access and implement
   'map_bus' callback to support it
 - Move 'pci_fixup_irqs' to before devices are added to the bus
 - Remove 'extern' from function prototype declared in the header

Changes from v4:
 - iProc PCIe driver module support was not included in patch series v4.
   This patch series (v5) fixes it

Changes from v3:
 - Export symbols of several PCI functions so they can be used by drivers
   compiled as kernel module
 - Add additional support to the Broadcom iProc PCIe driver so it can be
   installed/uninstalled as kernel loadable module

Changes from v2:
 - Major rework of the PCIe driver to factor out common generic code from
   front-end bus interface. Support for generic platform bus interface is
   also added
 - Adapt to several new PCI APIs that have been introduced lately

Changes from v1:
 - Add standard PCI interrupt DT properties "#interrupt-cells",
   "interrupt-map-mask" and "interrupt-map" so legacy INTx interrupts can be
   supported by using standard PCI OF IRQ parsing function
 - Get rid of custom IRQ mapping function in the driver. Use
   of_irq_parse_and_map_pci instead

Ray Jui (4):
  PCI: Export symbols of PCI functions
  pci: iProc: define iProc PCIe platform bus binding
  pci: iproc: Add Broadcom iProc PCIe support
  ARM: dts: enable PCIe support for Cygnus
