[PATCH V2 0/4] Add QFPROM support for few IPQ SoCs

[Kathiravan T]

Like any other SOCs, Qualcomm's IPQ SOCs also have an efuse region which
exposes the HW quirks like CPU Freq limit and so on. This series add the
basic support for the efuse. Feature specific fuses will be added along
with the feature set.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions. However, there's no need to repost patches *only* to add the
tags. The upstream maintainer will do that for acks received on the
version they apply.

https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540

If a tag was not added on purpose, please state why and what changed.

Best regards,
Krzysztof

It looks like the prng node name is incorrect. It should be qrng@e3000
instead of qrng@e1000. Could you please send a followup to fix it?

In case that wasn't clear, since I think this series will go in as-is,
that fix would be sent separately, on top of this.
