So how exactly does this interact with the existing sh_intc code? Or is
there some reason why you have opted to bypass it in order to implement a
simplified reduced-functionality version of INTC support focused only on
external pins? If both are used together this is going to be a nightmare
for locking, and it's also non-obvious how the IRQ domains on both sides
will interact.

This needs a lot more explanation.
