Detailed Description

struct irq_domain - Hardware interrupt number translation object Element in global irq_domain list. : Method used for reverse mapping hwirq numbers to linux irq. This will be one of the IRQ_DOMAIN_MAP_* values. : Revmap method specific data. : pointer to irq_domain methods : private data pointer for use by owner. Not touched by irq_domain core code. : Start of irq_desc range assigned to the irq_domain. The creator of the irq_domain is responsible for allocating the array of irq_desc structures. : Number of irqs managed by the irq domain : Starting number for hwirqs managed by the irq domain : (optional) Pointer to device tree nodes associated with the irq_domain. Used when decoding device tree interrupt specifiers.
