Heu I'm not the author of cpufreq-dt, so I'm not the best to answer.
To answer the question "without DT", it depends if you mean "with ACPI" or "with
platform_data" or something else.

>From what I've seen so far, the missing/blocking points are :
- the OPP points definition as you said
- probably same thing for the input power supply / regulator
- the cooling parts probably
- and more generaly all the cpufreq-dt is built around device-tree
- last point, the name from KConfig, "Generic DT based cpufreq driver"
=> that strongly suggest it's device-tree only

I'm deeply convinced that Viresh being one of the authors will shed more light
on this.

Cheers.
