It's easy to verify at least from the regulator PoV that > the voltage is scaled also. I had probed and verified voltage on beagle and beagle XM. OMAP4 obviously wont scale (as mentioned) due to the fact that vc-vp regulator is needed. > > My dumb DVFS test script (below) should work on any busybox rootfs thanks for the script. yep - I can use this as well, but given that probe did verify voltage scale on TWL5030 inductors, it might be redundant.
