--------------------------------------------------------------------------
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";
...
};
