STRUCT 
IRQ_CHIP_TYPE(9) 					    Structures						   STRUCT IRQ_CHIP_TYPE(9)

NAME

       struct_irq_chip_type - Generic interrupt chip instance for a flow type

SYNOPSIS

       struct irq_chip_type {
	 struct irq_chip chip;
	 struct irq_chip_regs regs;
	 irq_flow_handler_t handler;
	 u32 type;
       };

MEMBERS

       chip
	   The real interrupt chip which provides the callbacks

       regs
	   Register offsets for this chip

       handler
	   Flow handler associated with this chip

       type
	   Chip can handle these flow types

DESCRIPTION

       A irq_generic_chip can have several instances of irq_chip_type when it requires different functions and register offsets for different flow
       types.
