The change looks good to me.

Mark, I assume you want to take the regmap change. If so then feel free
to pull the prerequisites from

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-domain-24-08-09

into your tree. It's based on 6.11-rc1 and contains only the three
irqdomain core changes.

If you want me to carry the regmap change, please let me know.

Thanks,
