1NVIDIA Tegra186 BPMP thermal sensor
2
3In Tegra186, the BPMP (Boot and Power Management Processor) implements an
4interface that is used to read system temperatures, including CPU cluster
5and GPU temperatures. This binding describes the thermal sensor that is
6exposed by BPMP.
7
8The BPMP thermal node must be located directly inside the main BPMP node. See
9../firmware/nvidia,tegra186-bpmp.txt for details of the BPMP binding.
10
11This node represents a thermal sensor. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for details of the
12core thermal binding.

14Required properties:
15- compatible:
16    Array of strings.
17    One of:
18    - "nvidia,tegra186-bpmp-thermal"
19    - "nvidia,tegra194-bpmp-thermal"
20- #thermal-sensor-cells: Cell for sensor index.
21    Single-cell integer.
22    Must be <1>.
