   16   Mediatek's Keypad controller is used to interface a SoC with a matrix-type
   17   keypad device. The keypad controller supports multiple row and column lines.
   18   A key can be placed at each intersection of a unique row and a unique column.
   19   The keypad controller can sense a key-press and key-release and report the
   20   event using a interrupt to the cpu.
