Yes, we need some interface to know what the current voltages are for
each of the domain when verifying if dvfs is actually scaling voltage
or not. the other option is to use omapconf (not yet public and only
supports OMAP4) to see what the voltages are. Though omapconf is an
option, it shows what it's computation of voltage from vsel is, not
what the kernel internally thinks (vsel_uv functions) it is.
