INPUT_UNREGISTER_POL(9) 					  Input Subsystem					   INPUT_UNREGISTER_POL(9)

NAME

       input_unregister_polled_device - unregister polled device

SYNOPSIS

       void input_unregister_polled_device(struct input_polled_dev * dev);

ARGUMENTS

       dev
	   device to unregister

DESCRIPTION

       The function unregisters previously registered polled input device from input layer. Polling is stopped and device is ready to be freed
       with call to input_free_polled_device.

NAME

       struct_input_polled_dev - simple polled input device

SYNOPSIS

       struct input_polled_dev {
	 void * private;
	 void (* open) (struct input_polled_dev *dev);
	 void (* close) (struct input_polled_dev *dev);
	 void (* poll) (struct input_polled_dev *dev);
	 unsigned int poll_interval;
	 unsigned int poll_interval_max;
	 unsigned int poll_interval_min;
	 struct input_dev * input;
       };

MEMBERS

       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 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).

DESCRIPTION

       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.
