I have added Laxman Dewangan because he introduced this interrupts = <8 0>;
As this is for palmas interrupt controller, it does not use the second field for interrupt from RTC. So there is no really any polarity. It can be set to 0. The second argument will be used for GPIOs mainly. However, support need to be added on GPIO driver for rising/falling configuration. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
