So, I think adding power domain nodes should go in a separate patch. Adding power domain nodes can break the system, if powering ON/OFF of the given power domain is NOT taken care well. I can see ISP is one such case. With this series I can see S2R breaks [1] on 5250 chromebook with current mainline kernel (same applies for arndale and smdk5250, but I have tested on these boards yet) Doug , Abhilash, Tomasz any thoughts on this.
