+= UniPhier eFuse device tree bindings =
+
+This UniPhier eFuse must be under soc-glue.
+
+Required properties:
+- compatible: should be "socionext,uniphier-efuse"
+- reg: should contain the register base and length
+
+= Data cells =
+Are child nodes of efuse, bindings of which as described in
+bindings/nvmem/nvmem.txt
+
+Example:
+
+ soc-glue@5f900000 {
+ compatible = "socionext,uniphier-ld20-soc-glue-debug",
+ "simple-mfd";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0x0 0x5f900000 0x2000>;
+
+ efuse {
+ compatible = "socionext,uniphier-efuse",
+ "syscon";
+ reg = <0x100 0xf00>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* Data cells */
+ usb_mon: usb_mon {
+ reg = <0x154 0xc>;
+ };
+ };
+ };
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+Example:
+
+ usb {
+ ...
+ nvmem-cells = <&usb_mon>;
+ nvmem-cell-names = "usb_mon";
+ }
