Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.
You missed at least DT list (maybe more), so this won't be tested.
Please resend and include all necessary entries.
Subject - ignored comments.
This is a friendly reminder during the review process.
It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.
Thank you.

Place it like other bindings, so after required or before properties.
Anyway, what happened with all the properties you had here and should be
switched to generic ones?

Really... You did not respond to my feedback, so sending uncorrected
version feels like being ignored. :(

Thank you for your input. I appreciate your feedback, and I apologize for not
addressing all your previous comments. It seems I may have missed them.

I have decided to remove the properties and utilize the default register values
during initialization to clear memory validation faults, which I believe is a
better approach. I am not yet familiar with how to implement some of the
properties to switch to the userspace ABI, but for now, is it okay to exclude it
and plan to implement it for future support?

I sincerely apologize, it was an oversight on my part and I didn't mean to
ignore it, and I understand if it caused any problems. Moving forward, I will ensure
to thoroughly review and address all feedback provided.
