Rebased today to fix comment typos and drop a duplicate patch; no code changes.
----------------------------------------------------------------

Enumeration:

- Wait for device readiness after reset by polling Vendor ID and looking
for Configuration RRS instead of polling the Command register and
looking for non-error completions, to avoid hardware retries done for
RRS on non-Vendor ID reads (Bjorn Helgaas)

- Rename CRS Completion Status to RRS ('Request Retry Status') to match
PCIe r6.0 spec usage (Bjorn Helgaas)

- Clear LBMS bit after a manual link retrain so we don't try to retrain a
link when there's no downstream device anymore (Maciej W. Rozycki)

- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance to
use higher speeds (Maciej W. Rozycki)

- Wait for each level of downstream bus, not just the first, to become
accessible before restoring devices on that bus (Ilpo Järvinen)

- Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
without having to stomp on the core's pdev->dev.groups (Lukas Wunner)

Driver binding:

- Export pcim_request_region(), a managed counterpart of
pci_request_region(), for use by drivers (Philipp Stanner)

- Export pcim_iomap_region() and deprecate pcim_iomap_regions() (Philipp
Stanner)

- Request the PCI BAR used by xboxvideo (Philipp Stanner)

- Request and map drm/ast BARs with pcim_iomap_region() (Philipp Stanner)

MSI:

- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a single
IRQ line and cannot set the affinity of each MSI to a specific CPU core
(Marek Vasut)

- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl, xilinx-xdma,
and xilinx drivers to avoid 'IRQ: set affinity failed' warnings (Marek
Vasut)

Power management:

- Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
Dybcio)

PCI device hotplug:

- Remove unnecessary hpc_ops struct from shpchp (ngn)

- Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp (weiyufeng)

Virtualization:

- Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)

- Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS but
does provide ACS-like features (Subramanian Ananthanarayanan)

IOMMU:

- Add function 0 DMA alias quirk for Glenfly Arise audio function, which
uses the function 0 Requester ID (WangYuli)

NPEM:

- Add Native PCIe Enclosure Management (NPEM) support for sysfs control
of NVMe RAID storage indicators (ok/fail/locate/rebuild/etc) (Mariusz
Tkaczyk)

- Add support for the ACPI _DSM PCIe SSD status LED management, which is
functionally similar to NPEM but mediated by platform firmware (Mariusz
Tkaczyk)

Device trees:

- Drop minItems and maxItems from ranges in PCI generic host binding
since host bridges may have several MMIO and I/O port apertures (Frank
Li)

- Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
clocks (Krzysztof Kozlowski)

Altera PCIe controller driver:

- Convert altera DT bindings from text to YAML (Matthew Gerlach)

- Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same thing
and is what other drivers use (Jinjie Ruan)

Broadcom STB PCIe controller driver:

- Add DT binding maxItems for reset controllers (Jim Quinlan)

- Use the 'bridge' reset method if described in the DT (Jim Quinlan)

- Use the 'swinit' reset method if described in the DT (Jim Quinlan)

- Add 'has_phy' so the existence of a 'rescal' reset controller doesn't
imply software control of it (Jim Quinlan)

- Add support for many inbound DMA windows (Jim Quinlan)

- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)

- Add Broadcom 7712 DT description and driver support (Jim Quinlan)

- Sort enums, pcie_offsets[], pcie_cfg_data, .compatible strings for
maintainability (Bjorn Helgaas)

Freescale i.MX6 PCIe controller driver:

- Add imx6q-pcie 'dbi2' and 'atu' reg-names for i.MX8M Endpoints (Richard
Zhu)

- Fix a code restructuring error that caused i.MX8MM and i.MX8MP
Endpoints to fail to establish link (Richard Zhu)

- Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
outbound alignment requirement (Richard Zhu)

- Call phy_power_off() in the .probe() error path (Frank Li)

- Rename internal names from imx6_* to imx_* since i.MX7/8/9 are also
supported (Frank Li)

- Manage Refclk by using SoC-specific callbacks instead of switch
statements (Frank Li)

- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)

- Expand comments for erratum ERR010728 workaround (Frank Li)

- Use generic PHY APIs to configure mode, speed, and submode, which is
harmless for devices that implement their own internal PHY management
and don't set the generic imx_pcie->phy (Frank Li)

- Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver Root
Complex support (Richard Zhu)

Freescale Layerscape PCIe controller driver:

- Replace layerscape-pcie DT binding compatible fsl,lx2160a-pcie with
fsl,lx2160ar2-pcie (Frank Li)

address a DT checker warning (Frank Li)
