[2/7] ARM: tegra_defconfig: Enable CONFIG_DEVFREQ_THERMAL commit: 4302331fdf4440b96dba583384a0e2b759cb13bd Best regards,
Hi, Some hardware versions of NVIDIA Tegra SoCs support higher freqs and they are producing much more heat than the other versions. We found that CPU throttling may be not enough on devices like Asus Transformer TF700T, which is Tegra30 tablet device. This series adds thermal cooling support to the NVIDIA Tegra30+ devfreq which cools down SoC by throttling memory frequency on overheat.
