Take them through your tree with my Acked-by. Yes a branch would be
appreciated just in case.

There is also

      https://lore.kernel.org/all/20240529133446.28446-1-Jonathan.Cameron@huawei.com

which fiddles with the GIC but most of this is not irqchip code. No idea
how that is supposed to find it's way into the tree.

Thanks,
