+= Spreadtrum SC27XX PMIC eFuse device tree bindings =

+Required properties:
+- compatible: Should be one of the following.

+	"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 {

+		reg = <0>;
+		spi-max-frequency = <26000000>;

+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+Example:
+
+	thermal {

+		nvmem-cell-names = "calibration";
+	};
