nxp, because that's what you used in compatibles.

I don't see detailed changelog. What changed here?

Drop description, it's redundant. I did not ask to add it.

Anyway, my comment is unanswered. Don't ignore the emails you receive.

Can someone provide rationale for this?

OK, Reference Manual does not mention them but I see your SCU PD driver
actually registers such power domains.

Best regards,
