From: Andrea della Porta <andrea.porta@suse.com>
Date: 2025-08-12 08:48:51
Also in:
linux-devicetree, linux-pci, lkml
Subsystem:
broadcom bcm2711/bcm2835 arm architecture, broadcom bcm7xxx arm architecture, broadcom stb pcie driver, open firmware and flattened device tree bindings, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers:
Florian Fainelli, Jim Quinlan, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds
The devicetree compiler is complaining as follows:
arch/arm64/boot/dts/broadcom/rp1-nexus.dtsi:3.11-14.3: Warning (unit_address_vs_reg): /axi/pcie@1000120000/rp1_nexus: node has a reg or ranges property, but no unit name
/home/andrea/linux-torvalds/arch/arm64/boot/dts/broadcom/bcm2712-rpi-5-b.dtb: pcie@1000120000: Unevaluated properties are not allowed ('rp1_nexus' was unexpected)
Add the optional node that fix this to the DT binding.
