Yes I started thinking about that too. I think there is a requirement to do the scaling via the voltage processor for the higher modes. And there needs to be some way to automatically change to a lower OPP in some cases.
For normal OPPs, using the twl regulator directly should be OK.
For the higher modes, maybe we could pass the callback functions from arch/arm/mach-omap2/voltage.c for the twl regulator so the voltage processor hardware can handle them directly. Or add a separate regulator driver operating the voltages like Nishanth posted patches for earlier.
Regards,
Tony
