1* TWL4030's Keypad Controller device tree bindings
2
3TWL4030's Keypad controller is used to interface a SoC with a matrix-type
4keypad device. The keypad controller supports multiple row and column lines.
5A key can be placed at each intersection of a unique row and a unique column.
6The keypad controller can sense a key-press and key-release and report the
7event using a interrupt to the cpu.
