16 * struct input_polled_dev - simple polled input device
17 * @private: private driver data
18 * @flush: driver-supplied method that flushes device's state upon
20 * @poll: driver-supplied method that polls the device and posts
21 * input events (mandatory).
22 * @poll_interval: specifies how often the poll() method shoudl be called.
23 * @input: input device structire associated with the polled device.
24 * Must be properly initialized by the driver (id, name, phys, bits).
26 * Polled input device provides a skeleton for supporting simple input
27 * devices that do not raise interrupts but have to be periodically
28 * scanned or polled to detect changes in their state.
