There is a small thermal driver ( https://android.googlesource.com/kernel/tegra/+/b445e5296764d18861a6450f6851f25b9ca59dee/drivers/video/tegra/host/gk20a/therm_gk20a.c ) but it doesn't seem to do much. I believe that for Tegra we rely in SOCTHERM instead, but maybe Ken could confirm? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
