drivers/misc/lan966x_pci.dtso:42.22-46.7: Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/cpu_clk: missing or empty reg/ranges property
drivers/misc/lan966x_pci.dtso:48.22-52.7: Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/ddr_clk: missing or empty reg/ranges property
drivers/misc/lan966x_pci.dtso:54.22-58.7: Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/sys_clk: missing or empty reg/ranges property
drivers/misc/lan966x_pci.dtso:18.15-165.5: Warning (avoid_unnecessary_addr_size): /fragment@0/__overlay__: unnecessary #address-cells/#size-cells without "ranges", "dma-ranges" or child "reg" property
