Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Wait for device readiness after reset by polling Vendor ID and
looking for Configuration RRS instead of polling the Command
register and looking for non-error completions, to avoid hardware
retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)

- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)

- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)

- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)

pci_request_region(), for use by drivers (Philipp Stanner)

specific CPU core (Marek Vasut)

implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
warnings (Marek Vasut)

Merge branch 'pci/devres'

- Add pcim_add_mapping_to_legacy_table() and
pcim_remove_mapping_from_legacy_table() helper functions to simplify
devres iomap table (Philipp Stanner)

- Reimplement devres that take a bit mask of BARs in a way that can be used
to map partial BARs as well as entire BARs (Philipp Stanner)

- Deprecate pcim_iomap_table() and pcim_iomap_regions_request_all() in
favor of pcim_* request plus pcim_* mapping (Philipp Stanner)

- Add pcim_request_region(), a managed interface to request a single BAR
(Philipp Stanner)

- Use the existing pci_is_enabled() interface to replace the struct
devres.enabled bit (Philipp Stanner)

- Move the struct pci_devres.pinned bit to struct pci_dev (Philipp Stanner)

- Reimplement pcim_set_mwi() so it uses its own devres cleanup callback
instead of a special-purpose bit in struct pci_devres (Philipp Stanner)

- Add pcim_intx(), which is unambiguously managed, unlike pci_intx(), which
is managed if pcim_enable_device() has been called but unmanaged
otherwise (Philipp Stanner)

- Remove pcim_release(), which is no longer needed after previous cleanups
of pcim_set_mwi() and pci_intx() (Philipp Stanner)

- Add pcim_iomap_range(), a managed interface to map part of a BAR (Philipp
Stanner)

- Fix vboxvideo leak by using the new pcim_iomap_range() instead of the
unmanaged pci_iomap_range() (Philipp Stanner)

PCI: Document hybrid devres hazards

These functions:

pci_request_region()
pci_request_regions()
pci_request_regions_exclusive()
pci_request_selected_regions()
pci_request_selected_regions

PCI: Document hybrid devres hazards

These functions:

pci_request_region()
pci_request_regions()
pci_request_regions_exclusive()
pci_request_selected_regions()
pci_request_selected_regions_exclusive()
pci_intx()

are "hybrid" functions that are managed if pcim_enable_device() has been
called, but unmanaged otherwise.

This is confusing and has already caused a bug (in 8558de401b5f
("drm/vboxvideo: use managed pci functions")) because users believe all PCI
functions, such as pci_iomap_range(), can become managed that way, which is
not the case.

Add comments to the relevant functions' docstrings that warn users about
this behavior.
