If there was a followup here, I missed it ...
ISTR that it doesn't use (formal) operating points, and that a lot of the
basic SOC power savings (vs powering off the display or wifi) come from a
different kind of mechanism entirely. Namely, a combination of dynamic
tick with a modified system idle task, which enters one of the OMAP low
power modes during those long periods between clock ticks or other irqs.
That's one of the standard power saving schemes used on OMAP1 platforms
with Linux.
