---------------------------------------------------------------------------
-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 {

- compatible = "xlnx,zynqmp-firmware";
- method = "smc";

- nvmem_firmware {
- compatible = "xlnx,zynqmp-nvmem-fw";

-
- /* 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";
-
- ...
