Detailed Description

struct irq_domain_ops - Methods for irq_domain objects : Match an interrupt controller device node to a host, returns 1 on a match : Create or update a mapping between a virtual irq number and a hw irq number. This is called only once for a given mapping. : Dispose of such a mapping : Given a device tree node and interrupt specifier, decode the hardware irq number and linux irq type value.

Functions below are provided by the driver and called whenever a new mapping is created or an old mapping is disposed. The driver can then proceed to whatever internal data structures management is required. It also needs to setup the irq_desc when returning from map().
