Pull PCI updates from Bjorn Helgaas:
"Enumeration changes:
- Add _HPX Type 3 settings support, which gives firmware more
influence over device configuration (Alexandru Gagniuc)
- Support fixed bus numbers from bridge Enhanced Allocation
capabilities (Subbaraya Sundeep)
- Add "external-facing" DT property to identify cases where we
require IOMMU protection against untrusted devices (Jean-Philippe
Brucker)
- Enable PCIe services for host controller drivers that use managed
host bridge alloc (Jean-Philippe Brucker)
- Log PCIe port service messages with pci_dev, not the pcie_device
(Frederick Lawler)
- Convert pciehp from pciehp_debug module parameter to generic
dynamic debug (Frederick Lawler)
Peer-to-peer DMA:
- Add whitelist of Root Complexes that support peer-to-peer DMA
between Root Ports (Christian König)
Native controller drivers:
- Add PCI host bridge DMA ranges for bridges that can't DMA
everywhere, e.g., iProc (Srinath Mannam)
- Add Amazon Annapurna Labs PCIe host controller driver (Jonathan
Chocron)
- Fix Tegra MSI target allocation so DMA doesn't generate unwanted
MSIs (Vidya Sagar)
- Fix of_node reference leaks (Wen Yang)
- Fix Hyper-V module unload & device removal issues (Dexuan Cui)
- Cleanup R-Car driver (Marek Vasut)
- Cleanup Keystone driver (Kishon Vijay Abraham I)
- Cleanup i.MX6 driver (Andrey Smirnov)
Significant bug fixes:
- Reset Lenovo ThinkPad P50 GPU so nouveau works after reboot (Lyude
Paul)
- Fix Switchtec firmware update performance issue (Wesley Sheng)
- Work around Pericom switch link retraining erratum (Stefan Mätje)"
