I am using Samsung-exynos micro-controller...in this controller we have 6 power states they are
1) Normal
2) Idle
3) Deep-Idle
4) Stop
5) Deep-Stop
6) Sleep
But in linux Kenel we have only Four Power states, they are
1) Run
2) StandBy
3) ShutDown
4) Sleep
So my question is How the Linux kernel 4 power states are controlled Samsung-exynos micro-controller 6 power states. How its inter-linked?
Please Help me on this.
Thanks & Regards
Siva Krishna.
