* struct input_polled_dev - simple polled input device
* @private: private driver data
* @flush: driver-supplied method that flushes device's state upon
* opening (optional)
* @poll: driver-supplied method that polls the device and posts
* input events (mandatory).
* @poll_interval: specifies how often the poll() method shoudl be called.
* @input: input device structire 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.
