Subject: [PATCH v7 0/3] Add host controller drivers for Cavium ThunderX PCI
Date: Fri, 4 Mar 2016 14:31:45 -0800 [thread overview]
Message-ID: <1457130708-3231-1-git-send-email-ddaney.cavm@gmail.com> (raw)
From: David Daney <david.daney@cavium.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 v6: Updated 3/3 to support Thunder pass-2.x silicon.
Changes from v5: Added Acked-by Rob Herring for the device tree
binding in 3/3. Fixed typo and split large functions as suggested by
Bjorn Helgaas.
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
