Re: [PATCH 2/6] ARM: Tegra: Add CPU's OPPs for using cpufreq-cpu0 driver

You can certainly define the mapping table in DT where a specialized Tegra cpufreq driver could read it in and then map frequency to voltage. But that's a runtime decision, as Speedo and process ID are fuse values and can not be represented in DT.

The problem with this is that the hardware description now associates voltages with certain frequencies and even if they are not used by the Linux driver they are plain wrong.

Hmm. I understand. Then we probably need mach-tegra/opp.c to call opp_add() for all such OPPs.. Neither DT nor cpufreq driver are the right place for this.
