The 'ports' node is not supposed to have a 'reg' property at all, in fact, doing so will lead to dtc issuing warnings looking like these: arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:109.4-14: Warning (reg_format): /switch/ports:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1) arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dtb: Warning (pci_device_reg): Failed prerequisite 'reg_format' arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dtb: Warning (pci_device_bus_num): Failed prerequisite 'reg_format' arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dtb: Warning (i2c_bus_reg): Failed prerequisite 'reg_format' arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dtb: Warning (spi_bus_reg): Failed prerequisite 'reg_format' arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:106.9-149.5: Warning (avoid_default_addr_size): /switch/ports: Relying on default #address-cells value arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:106.9-149.5: Warning (avoid_default_addr_size): /switch/ports: Relying on default #size-cells value Fix the example by remove the stray 'reg' property.
