| 13 | description: | |
| 14 | In Tegra186, the BPMP (Boot and Power Management Processor) implements |
| 15 | an interface that is used to read system temperatures, including CPU |
| 16 | cluster and GPU temperatures. This binding describes the thermal |
| 17 | sensor that is exposed by BPMP. |
| 18 | |
| 19 | The BPMP thermal node must be located directly inside the main BPMP |
| 20 | node. See ../firmware/nvidia,tegra186-bpmp.yaml for details of the |
| 21 | BPMP binding. |
| 22 | |
| 23 | This node represents a thermal sensor. See |
| 24 | |
| 25 | Documentation/devicetree/bindings/thermal/thermal-sensor.yaml |
| 26 | |
| 27 | for details of the core thermal binding. |
