I will modify it in next version.

Do you mean need to add simple-bus like this?

+   soc: soc {
+                #address-cells = <0x1>;
+                #size-cells = <0x1>;
+                ranges = <0 0 0 0xffffffff>;
+                compatible = "simple-bus";

	        soc_data: soc_data@...00000 {
	                compatible = "mediatek,mt8183-efuse",
	                             "mediatek,efuse";
	                reg = <0 0x08000000 0 0x0010>;
	                #address-cells = <1>;
	                #size-cells = <1>;
	                status = "disabled";
	        };

	        gic: interrupt-controller@...00000 {
	                compatible = "arm,gic-v3";
	                #interrupt-cells = <4>;
