* omap4: reduce default operating point for 4460 devices
Reduce the operating point for 4460 to OPP100 (MPU at 700MHz)
From bug report:
With both A9 cores loaded 4460 reaches max temperature in about 30s at the
current operating point of 930MHz. The operating point should be lowered to
It appears the panda heats more than I thought (and much more that the blaze),
and by loading the 2 cores I can quite easily reach max temperature at 920MHz
(it takes around 30s on my board!).
At 700MHz, the temperature still increases but much slower. So if the A9 cores
do not run at 100% all the time we shall be ok.
So for now, we definitely need this change if we don't want to run with a
