-This binding is intended to represent MTK-EFUSE which is found in most Mediatek SOCs.
-
-Required properties:
-- compatible: should be
-	      "mediatek,mt7622-efuse", "mediatek,efuse": for MT7622
-	      "mediatek,mt7623-efuse", "mediatek,efuse": for MT7623

-	      "mediatek,mt8516-efuse", "mediatek,efuse": for MT8516

-= Data cells =
-Are child nodes of MTK-EFUSE, bindings of which as described in
-bindings/nvmem/nvmem.txt
-
-Example:
-
-	efuse: efuse at 10206000 {
-		compatible = "mediatek,mt8173-efuse";
-		reg	   = <0 0x10206000 0 0x1000>;

-		/* Data cells */
-		thermal_calibration: calib at 528 {
-			reg = <0x528 0xc>;
-		};
-	};
-
-= Data consumers =
-Are device nodes which consume nvmem data cells.
-
-For example:
-
-	thermal {
-		...
-		nvmem-cells = <&thermal_calibration>;
-		nvmem-cell-names = "calibration";
-	};
