It's fairly obvious in your gerrit patch <https://chromium-review.googlesource.com/#/c/220270/1/arch/arm/boot/dts/rk3xxx-cpu-thermal.dtsi> because gerrit (by default) shows you "tab" characters... In general you should use tab for indentation, not spaces. You seem to use a mix of the two. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-pm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It's better to name things after the first relevant product. I'd just name this "rk3288-cpu-thermal.dtsi". -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-pm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This patch changes a dtsi file to contain the thermal data on RK3288 and later SoCs. This data will enable a thermal shutdown over 125C.
