[PATCH v2 1/2] dt-bindings: PCI: kirin: fix bus-range

From: Mauro Carvalho Chehab
Date: Mon Aug 16 2021 - 15:53:35 EST


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.
