+= Rockchip eFuse device tree bindings =
+
+Required properties:
+- compatible: Should be "rockchip,rockchip-efuse"
+- reg: Should contain the registers location and exact eFuse size
+- clocks: Should be the clock id of eFuse
+- clock-names: Should be "pclk_efuse"
+
+= Data cells =
+Are child nodes of eFuse, bindings of which as described in
+bindings/nvmem/nvmem.txt
+
+Example:
+
+       efuse: efuse@ffb40000 {
+               compatible = "rockchip,rockchip-efuse";
+               reg = <0xffb40000 0x20>;
+               #address-cells = <1>;
+               #size-cells = <1>;
+               clocks = <&cru PCLK_EFUSE256>;
+               clock-names = "pclk_efuse";
+
+               /* Data cells */

+                       reg = <0x17 0x1>;
+               };
+       };
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+Example:
+
+       cpu_leakage {
+               ...
+               nvmem-cells = <&cpu_leakage>;
