From b1bf0efcd9a5f04ce154083637deafc754ef3c0f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 14 Apr 2026 08:47:46 +0200 Subject: [PATCH] ARM: dts: bcm4709: fix bus range assignment 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.
