3Required properties:
4- compatible: Should be one of the following.
5	"sprd,sc2720-efuse"
6	"sprd,sc2721-efuse"
7	"sprd,sc2723-efuse"
8	"sprd,sc2730-efuse"
9	"sprd,sc2731-efuse"
10- reg: Specify the address offset of efuse controller.
11- hwlocks: Reference to a phandle of a hwlock provider node.

13= Data cells =
14Are child nodes of eFuse, bindings of which as described in

43= Data consumers =
44Are device nodes which consume nvmem data cells.
