3Required properties:
4- compatible: Should be "sprd,ums312-efuse".
5- reg: Specify the address offset of efuse controller.
6- clock-names: Should be "enable".
7- clocks: The phandle and specifier referencing the controller's clock.
8- hwlocks: Reference to a phandle of a hwlock provider node.

10= Data cells =
11Are child nodes of eFuse, bindings of which as described in
12bindings/nvmem/nvmem.txt

14Example:
15
16	ap_efuse: efuse@32240000 {
17		compatible = "sprd,ums312-efuse";

29= Data consumers =
30Are device nodes which consume nvmem data cells.

37		nvmem-cells = <&thermal_calib>;
38		nvmem-cell-names = "calibration";
