In this respect it means, the device cannot wake-up the system from suspend state. Such devices are completely powered down/clock disabled in suspend state. Devices which have wakeup source like RTC are not powered down completely so as to generate a wakeup interrupt. This would try to wakeup the system. Sorry, I am not aware about "device without wakeup source" in terms of runtime pm.
