Subject: [PATCH v3 05/12] PCI: of_property: Assign PCI instead of CPU bus address to dynamic bridge nodes
When populating "ranges" property for a PCI bridge, of_pci_prop_ranges()
incorrectly use the CPU bus address of the resource. Since this is a PCI-PCI
bridge, the window should instead be in PCI address space. Call
pci_bus_address() on the resource in order to obtain the PCI bus
address.
