----------------------------------------------------------------
Resource management:
- Improve resource assignment for hot-added nested bridges, e.g.,
Thunderbolt (Nicholas Johnson)
Power management:
- Optionally print config space of devices before suspend (Chen Yu)
- Increase D3 delay for AMD Ryzen5/7 XHCI controllers (Daniel Drake)
Virtualization:
- Generalize DMA alias quirks (James Sewart)
- Add DMA alias quirk for PLX PEX NTB (James Sewart)
- Fix IOV memory leak (Navid Emamdoost)
AER:
- Log which device prevents error recovery (Yicong Yang)
Peer-to-peer DMA:
- Whitelist Intel SkyLake-E (Armen Baloyan)
Broadcom iProc host bridge driver:
- Apply PAXC quirk whether driver is built-in or module (Wei Liu)
Broadcom STB host bridge driver:
- Add Broadcom STB PCIe host controller driver (Jim Quinlan)
Intel Gateway SoC host bridge driver:
- Add driver for Intel Gateway SoC (Dilip Kota)
Intel VMD host bridge driver:
- Add support for DMA aliases on other buses (Jon Derrick)
- Remove dma_map_ops overrides (Jon Derrick)
- Remove now-unused X86_DEV_DMA_OPS (Christoph Hellwig)
NVIDIA Tegra host bridge driver:
- Fix Tegra30 afi_pex2_ctrl register offset (Marcel Ziswiler)
Panasonic UniPhier host bridge driver:
- Remove module code since driver can't be built as a module (Masahiro
Yamada)
Qualcomm host bridge driver:
- Add support for SDM845 PCIe controller (Bjorn Andersson)
TI Keystone host bridge driver:
- Fix "num-viewport" DT property error handling (Kishon Vijay Abraham I)

- Fix outbound region mapping (Yurii Monakov)
Misc:
- Add Switchtec Gen4 support (Kelvin Cao)
- Add Switchtec Intercomm Notify and Upstream Error Containment support
(Logan Gunthorpe)
- Use dma_set_mask_and_coherent() since Switchtec supports 64-bit
addressing (Wesley Sheng)
