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.
