NVIDIA Tegra186 BPMP thermal sensor
|
|
|
|
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.txt for details of the BPMP binding.
|
|
|
|
This node represents a thermal sensor. See thermal.txt for details of the
|
|
core thermal binding.
|
|
|
|
Required properties:
|
|
- compatible:
|
|
Array of strings.
|
|
One of:
|
|
- "nvidia,tegra186-bpmp-thermal".
|
|
- #thermal-sensor-cells: Cell for sensor index.
|
|
Single-cell integer.
|
|
Must be <1>.
|
|
|
|
Example:
|
|
|
|
bpmp {
|
|
...
|
|
|
|
bpmp_thermal: thermal {
|
|
compatible = "nvidia,tegra186-bpmp-thermal";
|
|
#thermal-sensor-cells = <1>;
|
|
};
|
|
};
