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.
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
23 This node represents a thermal sensor. See
25 Documentation/devicetree/bindings/thermal/thermal-sensor.yaml
