= 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"; |
|
|
|
... |
|
};
