  * struct input_polled_dev - simple polled input device
- * @private: private driver data
- * @flush: driver-supplied method that flushes device's state upon
- *      opening (optional)
+ * @private: private driver data.
+ * @open: driver-supplied method that prepares device for polling
+ *      (enabled the device and maybe flushes device state).
+ * @close: driver-supplied method that is called when device is no
+ *      longer being polled. Used to put device into low power mode.
  * @poll: driver-supplied method that polls the device and posts
  *      input events (mandatory).
- * @poll_interval: specifies how often the poll() method shoudl be called.
+ * @poll_interval: specifies how often the poll() method should be called.
+ *      Defaults to 500 msec unless overriden when registering the device.
+ * @poll_interval_max: specifies upper bound for the poll interval.
+ *      Defaults to the initial value of @poll_interval.
+ * @poll_interval_min: specifies lower bound for the poll interval.
+ *      Defaults to 0.
  * @input: input device structire associated with the polled device.
  *      Must be properly initialized by the driver (id, name, phys, bits).
