We have a better way to express this to avoid confusion. In your DTS file, using the new DTS preprocessor: #include <dt-bindings/interrupt-controller/irq.h> interrupt-parent = <&gpio6>; interrupts = <16 IRQ_TYPE_LEVEL_LOW>; Yours, Linus Walleij -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
