 Hi Ayan,
Yes, I know...This is exactly the point in PM I don't understand yet...
I try to configure the linux in my board to do it all automatically
(this are actually my requirements) , i.e. using the following
mechanism: cpuidle, cpufreq, DVFS & runtime PM.
Now, the thing I don't yet understand is what the wakeup source means
in this configuration. Wakeup only for a specific device driver ?
Thanks for clarification this issue for me....
