Members
mask
precomputed bitmask for accessing the chip registers
irq
interrupt number
hwirq
hardware interrupt number, local to the interrupt domain
common
point to data shared by all irqchips
chip
low level interrupt hardware access
domain
Interrupt translation domain; responsible for mapping between hwirq number and linux irq number.
parent_data
pointer to parent struct irq_data to support hierarchy irq_domain
chip_data
platform-specific per-chip private data for the chip methods, to allow shared chip implementations
