Fwd: External devices

Now, the thing I don't yet understand is what the wakeup source means in this configuration. Wakeup only for a specific device driver ? Wakeup source has its relevance mostly for system suspend/resume where in a device (eg keyboard) can pull the system out of suspend mode.

In Runtime-pm, the device is the wake-up source for itself unless there exist a parent-child relationship ie under some conditions the child can wakeup the parent. So there is no such relevance for wakeup device in runtime-pm
