13description: |
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.
