+description: |
+ Mediatek'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.
