That's the reason why the driver lacks the irq_set_wake() callback for the interrupt chip. But this prevent to properly enter power management states like "suspend to idle". Enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so the interrupt suspend logic can handle the chip correctly.
