+	{{.nvmem_cell_name = "socinfo-data1", .efuse_data = 0x81862001}},
+};

I'm *sure* that there's a way to avoid specifying the soc-specific compatible, as
the efuse_data is used only for validation, while what you do here is to simply
read the SoC ID from eFuse array.

In theory, this driver could simply have

compatible = "mediatek,socinfo";

as compatible string, without any SoC-specific string in the devicetree, at all,
so that the SoC ID would get recognized completely dynamically - and adding the
name and other strings would be a consequence.

+	{.soc_name = "MT8186T",
+	 .soc_segment_name = "MT8186TV/AZA",
+	 .marketing_name = "Kompanio 528"},
