Merge tag 'pci-v4.10-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:
 "PCI changes:

   - add support for PCI on ARM64 boxes with ACPI. We already had this
     for theoretical spec-compliant hardware; now we're adding quirks
     for the actual hardware (Cavium, HiSilicon, Qualcomm, X-Gene)

   - add runtime PM support for hotplug ports

   - enable runtime suspend for Intel UHCI that uses platform-specific
     wakeup signaling

   - add yet another host bridge registration interface. We hope this is
     extensible enough to subsume the others

   - expose device revision in sysfs for DRM

   - to avoid device conflicts, make sure any VF BAR updates are done
     before enabling the VF

   - avoid unnecessary link retrains for ASPM

   - allow INTx masking on Mellanox devices that support it

   - allow access to non-standard VPD for Chelsio devices

   - update Broadcom iProc support for PAXB v2, PAXC v2, inbound DMA,
     etc

   - update Rockchip support for max-link-speed

   - add NVIDIA Tegra210 support

   - add Layerscape LS1046a support

   - update R-Car compatibility strings

   - add Qualcomm MSM8996 support

   - remove some uninformative bootup messages"
