description: Supply Voltage Input
reset-gpios:
description:
If specified, it will be asserted during driver probe. As the line is
active low, it should be marked GPIO_ACTIVE_LOW.

maxItems: 1
gpio-controller:
description:
This property applies if either keypad,num-rows lower than 8 or
keypad,num-columns lower than 10.
'#gpio-cells':
const: 2
interrupt-controller:
description:
This property applies if either keypad,num-rows lower than 8 or
keypad,num-columns lower than 10. This property is optional if
keypad,num-rows or keypad,num-columns are not specified as the
device is then configured to be used purely for gpio during which
interrupts may or may not be utilized.
'#interrupt-cells':
const: 2
adi,unlock-keys:
description:
Specifies a maximum of 2 keys that can be used to unlock the keypad.
If this property is set, the keyboard will be locked and only unlocked
after these keys are pressed. If only one key is set, a double click is
needed to unlock the keypad. The value of this property cannot be bigger
or equal than keypad,num-rows * keypad,num-columns.
