+ * struct input_polled_dev - simple polled input device

+ * @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 should be called.
+ * Defaults to 500 msec unless overridden 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 structure associated with the polled device.
+ * Must be properly initialized by the driver (id, name, phys, bits).
+ *
+ * Polled input device provides a skeleton for supporting simple input
+ * devices that do not raise interrupts but have to be periodically
+ * scanned or polled to detect changes in their state.
