Using bus-range = <0 1> causes a runtime warning: [ 5.363450] pci_bus 0000:00: root bus resource [bus 00-01] [ 5.396998] pci_bus 0000:01: busn_res: can not insert [bus 01-ff] under [bus 00-01] (conflicts with (null) [bus 00-01]) [ 5.284831] pci 0000:00:00.0: PCI bridge to [bus 01-ff] On Kirin 960, changing to bus-range = <0 0xff> produces a cleaner log. Kirin 970 is more complex, so better to just drop bus-range as a hole.
