STRUCT 
MATRIX_KEYPAD(9) 					  Input Subsystem					   STRUCT MATRIX_KEYPAD(9)

NAME

       struct_matrix_keypad_platform_data - platform-dependent keypad data

SYNOPSIS

       struct matrix_keypad_platform_data {
	 const struct matrix_keymap_data * keymap_data;
	 const unsigned int * row_gpios;
	 const unsigned int * col_gpios;
	 unsigned int num_row_gpios;
	 unsigned int num_col_gpios;
	 unsigned int col_scan_delay_us;
	 unsigned int debounce_ms;
	 bool active_low;
	 bool wakeup;
	 bool no_autorepeat;
       };

MEMBERS

       keymap_data
	   pointer to matrix_keymap_data

       row_gpios
	   pointer to array of gpio numbers representing rows

       col_gpios
	   pointer to array of gpio numbers reporesenting colums

       num_row_gpios
	   actual number of row gpios used by device

       num_col_gpios
	   actual number of col gpios used by device

       col_scan_delay_us
	   delay, measured in microseconds, that is needed before we can keypad after activating column gpio

       debounce_ms
	   debounce interval in milliseconds

       active_low
	   gpio polarity

       wakeup
	   controls whether the device should be set up as wakeup source

       no_autorepeat
	   disable key autorepeat

DESCRIPTION

       This structure represents platform-specific data that use used by matrix_keypad driver to perform proper initialization.

STRUCT 
INPUT_POLLED_(9) 					  Input Subsystem					   STRUCT INPUT_POLLED_(9)

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.
