OSWR stands for Open Switch With Retention. This is one of the target power states where logic is lost for all the modules in the power domain except for the ones with Built in retention Flip Flops. This is the main difference between OFF and OSWR mode. Because of this feature, wake up latency for OSWR is lesser than OFF mode but more than CSWR (Closed Switch With Retention - where module logic retained).

Please explain what OSWR means, the patch description should be clear to everybody. I guess you mean Open SWitch Retention?
