Both NVIDIA Tegra20 and Tegra30 SoCs should be blacklisted because CPU OPPs use supported_hw and thus platdev isn't suitable for these SoCs. Currently cpufreq-dt driver produces a bit annoying warning splats during boot because valid OPPs are not found, this will be fixed once tegra20-cpufreq driver will be update to support cpufreq-dt. The warnings will also happen on older stable kernels using newer device-trees, thus this patch should be backported to stable kernels as well.
