Sharing interrupts on edge types is a > stupid idea, but hardware folks insist on implementing stupid ideas. When you say "That might work with level interrupts", what is "that" ? In my case, interrupt-map = <0 0 0 1 &irq0 54 IRQ_TYPE_LEVEL_HIGH>; interrupts = <54 IRQ_TYPE_LEVEL_HIGH>; Both ISRs expect LEVEL_HIGH. In fact, doesn't request_irq return an error if the triggers are different? Regards.
