Merge branch 'pci/enumeration'
- Add PCI_EXT_CAP_ID_PL_32GT define (Ben Dooks)
- Propagate firmware node by calling device_set_node() for better
modularity (Andy Shevchenko)
- Discover Data Link Layer Link Active Reporting earlier so quirks can take
advantage of it (Maciej W. Rozycki)
- Use cached Data Link Layer Link Active Reporting capability in pciehp,
powerpc/eeh, and mlx5 (Maciej W. Rozycki)
- Run quirk for devices that require OS to clear Retrain Link earlier, so
later quirks can rely on it (Maciej W. Rozycki)
- Export pcie_retrain_link() for use outside ASPM (Maciej W. Rozycki)
- Add Data Link Layer Link Active Reporting as another way for
pcie_retrain_link() to determine the link is up (Maciej W. Rozycki)
- Work around link training failures (especially on the ASMedia ASM2824
switch) by training first at 2.5GT/s and then attempting higher rates
(Maciej W. Rozycki)
* pci/enumeration:
PCI: Add failed link recovery for device reset events
PCI: Work around PCIe link training failures
PCI: Use pcie_wait_for_link_status() in pcie_wait_for_link_delay()
PCI: Add support for polling DLLLA to pcie_retrain_link()
PCI: Export pcie_retrain_link() for use outside ASPM
PCI: Export PCIe link retrain timeout
PCI: Execute quirk_enable_clear_retrain_link() earlier
PCI/ASPM: Factor out waiting for link training to complete
PCI/ASPM: Avoid unnecessary pcie_link_state use
PCI/ASPM: Use distinct local vars in pcie_retrain_link()
net/mlx5: Rely on dev->link_active_reporting
powerpc/eeh: Rely on dev->link_active_reporting
PCI: pciehp: Rely on dev->link_active_reporting
PCI: Initialize dev->link_active_reporting earlier
PCI: of: Propagate firmware node by calling device_set_node()
PCI: Add PCI_EXT_CAP_ID_PL_32GT define
