  * struct irq_data - per irq and irq chip data passed down to chip functions
  * @irq:                interrupt number
+ * @hwirq:              hardware interrupt number, local to the interrupt domain
  * @node:               node index useful for balancing
  * @state_use_accessors: status information for irq chip functions.
  *                      Use accessor functions to deal with it
  * @chip:               low level interrupt hardware access
+ * @domain:             Interrupt translation domain; responsible for mapping
+ *                      between hwirq number and linux irq number.
  * @handler_data:       per-IRQ data for the irq_chip methods
  * @chip_data:          platform-specific per-chip private data for the chip
  *                      methods, to allow shared chip implementations
