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