It would be more typical to order the patches with changes to tegra124.dtsi first, then changes to board files (that build on the core SoC support) second. > diff --git a/arch/arm/boot/dts/tegra124-jetson-tk1.dts b/arch/arm/boot/dts/tegra124-jetson-tk1.dts > + thermal-zones { > + cpu { > + trips { > + cpu-critical { Can we name that simply "critical"? DT node names are supposed to represent type of object more than identity of object. Even "critical" is a bit of an identity, and "trip@0" would be better, but I imagine the core thermal DT bindings precluded that? -- 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 adds critical trip points to the Jetson TK1 device tree. The device will do a controlled shutdown when either the CPU, GPU or MEM thermal zone reaches 101 degrees Celsius.
