    2 =  Zynq UltraScale+ MPSoC nvmem firmware driver binding =
    3 --------------------------------------------------------------------------
    4 The nvmem_firmware node provides access to the hardware related data
    5 like soc revision, IDCODE... etc, By using the firmware interface.
    6 
    7 Required properties:
    8 - compatible: should be "xlnx,zynqmp-nvmem-fw"
    9 
   10 = Data cells =
   11 Are child nodes of silicon id, bindings of which as described in
   12 bindings/nvmem/nvmem.txt

   14 -------
   15  Example
   16 -------
   17 firmware {
   18         zynqmp_firmware: zynqmp-firmware {
   19                 compatible = "xlnx,zynqmp-firmware";
   20                 method = "smc";
   21 
   22                 nvmem_firmware {
   23                         compatible = "xlnx,zynqmp-nvmem-fw";

   25                         #size-cells = <1>;
   26 
   27                         /* Data cells */

   31                 };
   32         };
   33 };
   34 
   35 = Data consumers =
   36 Are device nodes which consume nvmem data cells.
   37 
   38 For example:
   39         pcap {
   40                 ...
   41 
   42                 nvmem-cells = <&soc_revision>;
   43                 nvmem-cell-names = "soc_revision";
   44 
   45                 ...
   46         };
