I think it makes sense to always enable it for GPIOs used as interrupts (regardless whether it is edge or level). -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
