+= Zynq UltraScale+ MPSoC nvmem firmware driver binding =

+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:
+
+ nvmem_firmware {

+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* Data cells */
+ soc_revision: soc_revision@0 {

+ };
+ };
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+For example:
+
+ pcap {
+ ...
+ nvmem-cells = <&soc_revision>;
+ nvmem-cell-names = "soc_revision";
+ };
