[PATCH v8 0/3] pci: iproc: Add Broadcom iProc PCIe support

From: Ray Jui
Date: Wed Apr 08 2015 - 14:18:48 EST

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 v7:
- Consolidate iProc PCIe patches and rebase to v4.0-rc1 per request
from Bjorn
- Restrict CONFIG_PCIE_IPROC to ARM based platforms
- Spell out 'pltfm' as 'platform'

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
