• 781d0f46d   irq_domain: Standardise legacy/linear domain selection ... Browse Code »

  A large proportion of interrupt controllers that support legacy mappings
  do so because non-DT systems need to use fixed IRQ numbers when registering
  devices via buses but can otherwise use a linear mapping. The interrupt
  controller itself typically is not affected by the mapping used and best
  practice is to use a linear mapping where possible so drivers frequently
  select at runtime depending on if a legacy range has been allocated to
  them.

  Standardise this behaviour by providing irq_domain_register_simple() which
  will allocate a linear mapping unless a positive first_irq is provided in
  which case it will fall back to a legacy mapping. This helps make best
  practice for irq_domain adoption clearer.
