10 * @active_low: %true indicates that button is considered
11 * depressed when gpio is low
12 * @desc: label that will be attached to button's gpio
13 * @type: input event type (%EV_KEY, %EV_SW, %EV_ABS)
14 * @wakeup: configure the button as a wake-up source

16 * @can_disable: %true indicates that userspace is allowed to
17 * disable button via sysfs
18 * @value: axis value for %EV_ABS
19 * @irq: Irq number in case of interrupt keys
