=  Zynq UltraScale+ MPSoC nvmem firmware driver binding =
--------------------------------------------------------------------------
The nvmem_firmware node provides access to the hardware related data
like soc revision, IDCODE... etc, By using the firmware interface.

Required properties:
- compatible: should be "xlnx,zynqmp-nvmem-fw"

= Data cells =
Are child nodes of silicon id, bindings of which as described in
bindings/nvmem/nvmem.txt

-------
 Example
-------
firmware {
	zynqmp_firmware: zynqmp-firmware {
		compatible = "xlnx,zynqmp-firmware";
		method = "smc";

		nvmem_firmware {
			compatible = "xlnx,zynqmp-nvmem-fw";
			#address-cells = <1>;
			#size-cells = <1>;

			/* Data cells */
			soc_revision: soc_revision {
				reg = <0x0 0x4>;
			};
		};
	};
};

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

For example:
	pcap {
		...

		nvmem-cells = <&soc_revision>;
		nvmem-cell-names = "soc_revision";

		...
	};
