-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 {

-};
-
-= Data consumers =
-Are device nodes which consume nvmem data cells.
-
-For example:
-	pcap {
