6 * Note, all properties are considered as u8 arrays.
7 * To get a value of any of them the caller must use device_property_read_u8_array().
6 * Properties are stored either as:
7 * u8 arrays which can be retrieved with device_property_read_u8_array() or
8 * booleans which can be queried with device_property_present().
