This patch changes the dtsi entry on omap4430 to contain
the thermal data. This data will enable the passive
cooling with CPUfreq cooling device at 100C and the
system will do a thermal shutdown at 125C.

2 cents:
we might want to move bandgap under ocp?

Yes, agreed. But I don't think this change is related to this patch or
to this series.

Correct - this comment is not related to the current patch, hence my 2
cents ;) - will be nice to have it cleaned up though..
