+ * struct gpio_extcon_platform_data - A simple GPIO-controlled extcon device.
+ * @name        The name of this GPIO extcon device.
+ * @gpio        Corresponding GPIO.
+ * @debounce    Debounce time for GPIO IRQ in ms.
+ * @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.
