Example:
interrupts-extended = <&intc1 5 1>, <&intc2 1 0>;
-A device node may contain either "interrupts" or "interrupts-extended", but not
-both. If both properties are present, then the operating system should log an
-error and use only the data in "interrupts".

+
+Additionally to the properties specified in the above standards a host bridge
+driver implementation may support the following properties:
+
+- linux,pci-domain:
+ If present this property assigns a fixed PCI domain number to a host bridge,
+ otherwise an unstable (across boots) unique number will be assigned.
+ It is required to either not set this property at all or set it for all
+ host bridges in the system, otherwise potentially conflicting domain numbers
+ may be assigned to root buses behind different host bridges. The domain
+ number for each host bridge in the system must be unique.
