   2 * irq_domain - IRQ translation domains
   3 *
   4 * Translation infrastructure between hw and linux irq numbers.  This is
   5 * helpful for interrupt controllers to implement mapping between hardware
   6 * irq numbers and the Linux irq number space.
   7 *
   8 * irq_domains also have hooks for translating device tree or other
   9 * firmware interrupt representations into a hardware irq number that
  10 * can be mapped back to a Linux irq number without any extra platform
  11 * support code.
  12 *
  13 * Interrupt controller "domain" data structure. This could be defined as a
  14 * irq domain controller. That is, it handles the mapping between hardware
  15 * and virtual interrupt numbers for a given interrupt domain. The domain
  16 * structure is generally created by the PIC code for a given PIC instance
  17 * (though a domain can cover more than one PIC if they have a flat number
  18 * model). It's the domain callbacks that are responsible for setting the
  19 * irq_chip on a given irq_desc after it's been mapped.
  20 *
  21 * The host code and data structures use a fwnode_handle pointer to
  22 * identify the domain. In some cases, and in order to preserve source
  23 * code compatibility, this fwnode pointer is "upgraded" to a DT
  24 * device_node. For those firmware infrastructures that do not provide
  25 * a unique identifier for an interrupt controller, the irq_domain
  26 * code offers a fwnode allocator.
