This seems to be wrong since the device supports deep-sleep mechanism [1] which requires a reset to leave it. Also some designs won't use the touchscreen as wakeup-source. According discussion [2] we decided to break backward compatibility and go the common way by using the 'wakeup-source' device-property.
