+= Spreadtrum SC27XX PMIC eFuse device tree bindings =
+
+Required properties:
+- compatible: Should be one of the following.
+	"sprd,sc2720-efuse"
+	"sprd,sc2721-efuse"
+	"sprd,sc2723-efuse"
+	"sprd,sc2730-efuse"
+	"sprd,sc2731-efuse"
+- reg: Specify the address offset of efuse controller.
+- hwlocks: Reference to a phandle of a hwlock provider node.
+
+= Data cells =
+Are child nodes of eFuse, bindings of which as described in
+bindings/nvmem/nvmem.txt
+
+Example:
+
+	sc2731_pmic: pmic@0 {
+		compatible = "sprd,sc2731";
+		reg = <0>;
+		spi-max-frequency = <26000000>;
+		interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-controller;
+		#interrupt-cells = <2>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		efuse@380 {
+			compatible = "sprd,sc2731-efuse";
+			reg = <0x380>;
+			#address-cells = <1>;
+			#size-cells = <1>;
+			hwlocks = <&hwlock 12>;
+
+			/* Data cells */
+			thermal_calib: calib@10 {
+				reg = <0x10 0x2>;
+			};
+		};
+	};
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+Example:
+
+	thermal {
+		...
+		nvmem-cells = <&thermal_calib>;
+		nvmem-cell-names = "calibration";
+	};
