[GIT PULL] PCI changes for v4.10
From: Bjorn Helgaas
Date: Thu Dec 15 2016 - 15:24:33 EST
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.
