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