Subject: [PATCH v5 0/3] Add host controller drivers for Cavium ThunderX PCI

From: David Daney <david.daney@...ium.com>

Some Cavium ThunderX processors require quirky access methods for the
config space of the PCIe bridge.

There are now three patches:

1) Refactor code in pci-host-generic so that it can more easily be
   used by other drivers.  This splits the driver for CAM and ECAM
   access methods to a separate file from the common host driver code.

2) Add the ThunderX PCIe driver to external PCIe buses, which
   leverages the code in pci-host-generic

3) Add ThunderX PCI driver for internel SoC buses used on early
   ThunderX chip revisions.

Changes from v4: Added patch 3/3.  Stylistic changes to 2/3 suggested
by Bjorn Helgaas.  When expanding config write width to 32-bits, mask
out unintened writes to W1C bits, also suggested by Bjorn Helgaas.

Changes from v3: Add some Acked-by, rebased to v4.5.0-rc1

Changes from v2: Improve device tree binding example as noted by Rob
Herring.  Rename pcie-thunder-pem.* to pci-thunder-pem.* for better
consistency.  Update MAINTAINERS to reflect the changes.

Changes from v1: Split CAM and ECAM code from common driver code as
suggested by Arnd Bergmann.  Fix spelling errors in
pcie-thunder-pem.txt

David Daney (3):
  PCI: generic: Refactor code to enable reuse by other drivers.
  pci, pci-thunder-pem: Add PCIe host driver for ThunderX processors.
  pci, pci-thunder-ecam: Add driver for ThunderX-pass1 on-chip devices
