+ * @irq_flags	IRQ Flags (e.g., IRQF_TRIGGER_LOW).
+ * @state_on	print_state is overriden with state_on if attached. If Null,
+ *		default method of extcon class is used.
+ * @state_off	print_state is overriden with state_on if detached. If Null,
+ *		default method of extcon class is used.
+ *
+ * Note that in order for state_on or state_off to be valid, both state_on
+ * and state_off should be not NULL. If at least one of them is NULL,
+ * the print_state is not overriden.
