2fa39159b6 Documentation/devicetree: Add PCIe max-link-speed property
Some of the host drivers have the requirement of knowing whether the EP
would never train at some link speed at all.  For instance, on some boards,
the link won't train at 5 GT/s but the host driver still sacrifice some
cycles to wait for the result of training at 5 GT/s as the host could
actually support 5 GT/s.  So we could parse this new property and make the
host drivers be aware of these cases.

2801f7252d PCI: Add missing DT binding for "linux,pci-domain" property
41e5c0f81d ("of/pci: Add pci_get_new_domain_nr() and
of_get_pci_domain_nr()") added parsing of the "linux,pci-domain" property,
but didn't add the binding documentation.

Since this property will be supported by a number of host bridge drivers,
add it to the common PCI binding doc.

Fixes: 41e5c0f81d ("of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()")
