Not really.. we cannot make 1.5GHz work without ABB integration into the transition sequence[1] - what we can try to do is make basic dvfs work. the approach we'd be taking (if we introduce tps handlers) is to do exactly what we did in 3.0/3.4 kernels. I am not too happy with that. instead, I would prefer we skip dvfs for 4460(which was never working in upstream) and do it the *right* way - which ever the upstream maintainers want it to be. that is my personal 2 cents.
