Hi Linus,

Sorry for the constant spam on this..

To me this looks like your IRQ handler is firing for unused IRQs, i.e.
you are getting spurious IRQs.

Are you missing to disable all IRQs as part of the set-up before
registering the GPIO chip? (Usually some registers need to
be written with zeroes.)

Changing the handler to handle_edge_irq() on the gpio side resolves
the issue and gpiomon registers edges from the gpio like it should.
So I think it's an ordering thing. Something like the gpio side sets
the handler to handle_bad_irq() after the irqchip side sets it to
handle_edge_irq().

Thanks for the help.

Cheers,

Daniel
