OPP2 and OPP3 are respectively at 1.15 and 1.06 or there abouts if I am not wrong -> since VDD2 essentially drives core domain (including L3 and SDRAM as a result), you really don't want to move the voltage lower without considering the implications. Smartreflex is the guy who can measure various points on OMAP and decide if the voltage can safely be lowered without impacting device behavior. > hard time figuring out how to do that in the linux-omap (non-PM) tree. > I grepped in (admittedly 2.6.29) arch/arm/mach-omap2 and it only > returned hits that seem to be related to smartreflex.

Can it be lowered globally or should it be guarded with an > machine_is_omap3beagle() clause? I don't think this is even valid.
