Does not the following: "Nodes that describe devices which generate interrupts must contain an "interrupts" property, an "interrupts-extended" property, or both. If both are present, the latter should take precedence; the former may be provided simply for compatibility with software that does not recognize the latter." already makes it clear that 'interrupts-extended' is the preferred way to represent interrupts? -- Florian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
