/**
* 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).
