First of all IRQCHIP_SKIP_SET_WAKE is not a valid irq_gc_flags and thus should not be passed as the last argument of irq_alloc_domain_generic_chips. Then pass the correct handler (handle_fasteoi_irq) to irq_alloc_domain_generic_chips instead of manually re-setting it in the initialization loop. And eventually initialize default irq flags to the pseudo standard: IRQ_REQUEST | IRQ_PROBE | IRQ_AUTOEN. Signed-off-by: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx> --- Hello Kevin, This patch has not been tested yet but it should solve the issue you've experienced with the IRQ_GC_BE_IO flag and the atmel-aic driver. I'll test it tomorrow and let you know if it actually works.
