= 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 location 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>;

#address-cells = <1>;
#size-cells = <1>;
/* Data cells */
usb_mon: usb-mon@54 {
reg = <0x54 0xc>;
};
};
};
= Data consumers =
Are device nodes which consume nvmem data cells.
Example:
usb {
...
nvmem-cells = <&usb_mon>;
nvmem-cell-names = "usb_mon";
}
