It seem strange to me that the driver uses "handle_edge_irq", given

I had trouble finding who/where sets .irq_ack() callback, which AFAIU
is mandatory for handle_edge_irq().

Yes that looks strange.

Neil have you tested IRQs with this code?

If there is trouble, please follow up with a fix for the edge handler.
Maybe it should just be handle_simple_irq().
