Hey everyone, I'll be attending CCCamp next month near Berlin, Germany. I'll be presenting Replicant and the various issues related to freedom and privacy/security on mobile devices there.

The hard part is that there's not a single reference design there. There's some pattern, but it's not at all something that can be made generic, because to a few exceptions, no one uses the same regulator to power the same thing, and with the same constraints (that directly depend on the stuff that you have connected on the other end of the regulator). So any mechanical change is not something that can be done. Especially for something that might blow up your board.

Basically yes. The point that Chen-Yu made is that he and other developers don't have all boards available to verify that all of these boards use the same layout for their wiring. Therefore they just leave these bits out. I'm actually working on a small patch to add these regulator bits to the BananaPi and possibly BananaPro dts files. I will post it soon, when I gathered enough information to ensure everything works fine. But anyway, we're getting offtopic here. So let's postpone this discussion until then.

I think what Maxime was trying to say is, that while all of your boards support Cpufreq, only the Cubietruck supports voltage scaling because only Cubietruck has the power regulator nodes defined in it's dts file (just have a look at the last lines of the Cubitruck dts file and compare that to the dts file, let's say, for Bananapi).

lsmod output on 4.1 kernel is attached. There's a bunch of cpufreq stuff but cpufreq-dt is not listed. I loaded that module but cpufreq is still not there (see second attached file).
