= Zynq UltraScale+ MPSoC nvmem firmware driver binding =
|
|
--------------------------------------------------------------------------
|
|
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";
|
|
|
|
...
|
|
};
