Hi Frank, After apply this patch, we found some dtbs_check error with the following patch which adds the PCIe node for MT8195: https://lore.kernel.org/linux-pci/20221020111925.30002-3-tinghan.shen@xxxxxxxxxxxx/ arch/arm64/boot/dts/mediatek/mt8195-cherry-tomato-r2.dtb: pcie@112f0000 : clock-names: 5: 'top_133m' was expected From schema: Documentation/devicetree/bindings/pci/mediatek-pcie- gen3.yaml arch/arm64/boot/dts/mediatek/mt8195-cherry-tomato-r2.dtb: pcie@112f8000 : clock-names: 5: 'top_133m' was expected From schema: Documentation/devicetree/bindings/pci/mediatek-pcie- gen3.yaml Did you get the same error when adding the PCIe node for MT7986?
