Node names should be generic. See also an explanation and list of examples
(not exhaustive) in DT specification:

basics.html#generic-names-recommendation
[Kundanala, Praveen Teja] Okay


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

It does not look like you tested the DTS against bindings. Please run `make
dtbs_check W=1` (see Documentation/devicetree/bindings/writing-schema.rst
or https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-
sources-with-the-devicetree-schema/
for instructions).
[Kundanala, Praveen Teja] Missed it, Will run and send V3.

#address-cells = <1>;
#size-cells = <1>;

- soc_revision: soc_revision@0 {
+ soc_revision: soc-revision@0 {
reg = <0x0 0x4>;
};

Wasn't this fixed already by Michal?
[Kundanala, Praveen Teja] Took base on Srinivas for-next repo and Michal's changes were not reflected in that repo.

Feel free to drop this from series that it can go via nvmem tree directly.
And when this is merged we can add just this patch via my tree.

Thanks,
Michal
