Subject: [GIT PULL] PCI changes for v5.2
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)

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)
