The driver recognizes standard "wakeup-source" property and there are DTS files using it. Add the property to the binding.

GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
|
|
The matrix keypad supports multiple row and column lines, a key can be
|
|
placed at each intersection of a unique row and a unique column. The matrix
|
|
keypad can sense a key-press and key-release by means of GPIO lines and
|
|
report the event using GPIO interrupts to the cpu.
