Sensors are placed across the die to gauge the17 temperature of the whole chip. The TSENSOR module:18 19 Generates an interrupt to SW to lower temperature via DVFS on reaching20 a certain thermal/voltage threshold.21 22 Generates a signal to the CAR to reduce CPU frequency by half on reaching23 a certain thermal/voltage threshold.24 25 Generates a signal to the PMC when the temperature reaches dangerously high26 levels to reset the chip and sets a flag in the PMC.27 28 TSENSOR has two channels which monitor two different spots of the SoC.29 30$ref: thermal-sensor.yaml#31 32properties:33 compatible:34 const: nvidia,tegra30-tsensor35 36 reg:37 maxItems: 138 39 clocks:40 maxItems: 141 42 resets:43 maxItems: 144 45 interrupts:46 maxItems: 147 48 "#thermal-sensor-cells":49 const: 150 51required:52 - compatible53 - reg54 - clocks55 - resets56 - interrupts57 58unevaluatedProperties: false59 60examples:61 - |62 thermal-sensor@70014000 {63 compatible = "nvidia,tegra30-tsensor";64 reg = <0x70014000 0x500>;65 interrupts = <0 102 4>;66 clocks = <&clk 100>;67 resets = <&rst 100>;68 69 #thermal-sensor-cells = <1>;70 };71
