14     +Nodes that describe devices which generate interrupts must contain an
15     +"interrupts" property, an "interrupts-extended" property, or both. If both are
16     +present, the latter should take precedence; the former may be provided simply
17     +for compatibility with software that does not recognize the latter. These
18     +properties contain a list of interrupt specifiers, one per output interrupt. The
19     +format of the interrupt specifier is determined by the interrupt controller to
20     +which the interrupts are routed; see section 2 below for details.
