Hi Krzysztof,

I will make sure to add backward compatibility in the reset driver in
the next version.

Thanks,

Tomer

Hi Krzysztof

Sorry but I didn't ignore your comment.

For not breaking exciting boards I add the following patch in V2
https://lore.kernel.org/linux-arm-kernel/20220608095623.22327-11-tmaimon77@gmail.com/ (local)
No, it does not solve it.
1. Patchset goes via separate trees (DTS are always separate), so it is
not bisectable. One of the branches/trees will have broken DTS.

2. All out of tree DTSes are broken. This is expressed as ABI and - with
some reasonable exceptions - you should not break it.
https://elixir.bootlin.com/linux/v5.19-rc1/source/Documentation/devicetree/bindings/ABI.rst

You have to keep backwards compatibility, so parse/handle both versions
of DTS.


Best regards,
Krzysztof
