OpPoint does not have any integration with voltage/clock framework idea what is completely unaccepted considering the announced goals for OpPoint. Yes, clock/voltage framework is separate entity and PowerOP does not do the job of clock/voltage framewrok because PowerOP is completely different layer. But PowerOP is only a part of PM framework Matt and I are proposing and PowerOP leverages clock/voltage framework as the lowest layer in the PM framework - PowerOP sits on top of PM Core while PM Core interacts directly with clock/voltage framework (please see PM framework architecture picture overview in my patch set postings). Clock framework is implemented for omap1/2 arches and is utilized by PM Core for omap in my previous posts of PowerOP.
