 16  * struct input_polled_dev - simple polled input device
 17  * @private: private driver data.
 18  * @open: driver-supplied method that prepares device for polling
 19  *      (enabled the device and maybe flushes device state).
 20  * @close: driver-supplied method that is called when device is no
 21  *      longer being polled. Used to put device into low power mode.
 22  * @poll: driver-supplied method that polls the device and posts
 23  *      input events (mandatory).
 24  * @poll_interval: specifies how often the poll() method should be called.
 25  *      Defaults to 500 msec unless overridden when registering the device.
 26  * @poll_interval_max: specifies upper bound for the poll interval.
 27  *      Defaults to the initial value of @poll_interval.
 28  * @poll_interval_min: specifies lower bound for the poll interval.
 29  *      Defaults to 0.
 30  * @input: input device structure associated with the polled device.
 31  *      Must be properly initialized by the driver (id, name, phys, bits).
 32  *
 33  * Polled input device provides a skeleton for supporting simple input
 34  * devices that do not raise interrupts but have to be periodically
 35  * scanned or polled to detect changes in their state.
