:) I wish that were the case, from an SoC entitlement point of view,
purely controlling frequency and regulator is not sufficent for
most OMAPs/AM variants. We do have to deal with ABB and AVS (now a
multitude of class variants to deal with) - part of the rationale for
switching to generic cpufreq as part of DT steps is to force ourselves to
adhere to common code and entitle required SoC feature set.

If you get a chance, it would be nice to hear your views on the intermediate
step(the patch series pointed above) as part of overall OMAP transition to DT.
