     1 NVIDIA Tegra186 BPMP thermal sensor
    2 
    3 In Tegra186, the BPMP (Boot and Power Management Processor) implements an
    4 interface that is used to read system temperatures, including CPU cluster
    5 and GPU temperatures. This binding describes the thermal sensor that is
    6 exposed by BPMP.
    7 
    8 The 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 
   11 This node represents a thermal sensor. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for details of the
   12 core thermal binding.
   13 
   14 Required 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>.
   23 
   24 Example:
   25 
   26 bpmp {
   27         ...
   28 
   29         bpmp_thermal: thermal {
   30                 compatible = "nvidia,tegra186-bpmp-thermal";
   31                 #thermal-sensor-cells = <1>;
   32         };
   33 };
