Are you sure 28 is the correct number in the irqpin IRQ space? Seems
strange to me. Should be 1 perhaps (counting from 0), or 2 - not sure how
that mapping would look like.

Not functionally. Spurious interrupts occur on sh73a0, the sense bitfield
is needed for r8a7779. But the latter won't apply without the former,
that's right.

No, not yet.
