PATCH v2 1/1 ARM: dts: bcm4709: fix bus range assignment
From: Arnd Bergmann <[email protected]>
The netgear r8000 dts file limits the bus range for the first host bridge to exclude bus 0, but the two devices on the first bus are explicitly assigned to bus 0, causing a build time warning:
/home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@1,0:bus-range: PCI bus number 0 out of range, expected (1 - 255) /home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@2,0:bus-range: PCI bus number 0 out of range, expected (1 - 255)
As Rosen mentioned, the bus-range property was a mistake, so just remove it and keep the reg values pointing to bus 0, which is allowed by the default bus range of the SoC.
