35 irq_domain 库在 irq_alloc_desc*() API 的基础上增加了 hwirq 和 IRQ 号码
39 irq_domain还实现了从抽象的irq_fwspec结构体到hwirq号的转换（到目前为止是
50 在大多数情况下，irq_domain在开始时是空的，没有任何hwirq和IRQ号之间的映射。
52 irq_domain和一个hwirq号作为参数。 如果hwirq的映射还不存在，那么它将分配
53 一个新的Linux irq_desc，将其与hwirq关联起来，并调用.map()回调，这样驱动
58 - irq_resolve_mapping()返回一个指向给定域和hwirq号的irq_desc结构指针，
61 - irq_find_mapping()返回给定域和hwirq的Linux IRQ号，如果没有映射则返回0。
65 - generic_handle_domain_irq()处理一个由域和hwirq号描述的中断。
72 如果驱动程序有Linux的IRQ号或irq_data指针，并且需要知道相关的hwirq号（比
