In the cover letter I see:

"This means Linux can no longer perform various system operations (e.g.
clock, power domain, and reset control)"

I skimmed through the rest including bindings, and I do not see how you
did it differently. Patchset is mixing multiple subsystems and topics,
so it does not make easier to find what you meant.

Can you point me directly how did you do it differently? And by "it" I
mean what you comment here - "such big differences between ... "?

Best regards,
