- * @match: Match an interrupt controller device node to a domain, returns

- * @select: Match an interrupt controller fw specification. It is more generic
- * than @match as it receives a complete struct irq_fwspec. Therefore,
- * @select is preferred if provided. Returns 1 on a match.
- * @map: Create or update a mapping between a virtual irq number and a hw
- * irq number. This is called only once for a given mapping.
- * @unmap: Dispose of such a mapping
- * @xlate: Given a device tree node and interrupt specifier, decode
- * the hardware irq number and linux irq type value.
- * @alloc: Allocate @nr_irqs interrupts starting from @virq.
- * @free: Free @nr_irqs interrupts starting from @virq.
- * @activate: Activate one interrupt in HW (@irqd). If @reserve is set, only
- * reserve the vector. If unset, assign the vector (called from
- * request_irq()).
- * @deactivate: Disarm one interrupt (@irqd).
- * @translate: Given @fwspec, decode the hardware irq number (@out_hwirq) and
- * linux irq type value (@out_type). This is a generalised @xlate
- * (over struct irq_fwspec) and is preferred if provided.
- * @debug_show: For domains to show specific data for an interrupt in debugfs.
