The ethernet-switch node does not have children with unit addresses, so address/size-cells are not really correct, as reported by dtc W=1 warning: armada-3720-eDPU.dts:26.19-60.4: Warning (avoid_unnecessary_addr_size): /soc/internal-regs@d0000000/mdio@32004/switch@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property This probably also fixes dtbs_check warning, but I could not find it, so not sure about that.
