Since the device can now function in a purely gpio mode, the following keypad specific properties are now made optional: - interrupts - keypad,num-rows - keypad,num-columns - linux,keymap However the above properties are required to be specified when configuring the device as a keypad, dependencies have been added such that specifying either one would require the remaining as well. Note that interrupts are optional, but required when the device has been configured in keypad mode.
