    description:
      Qualcomm TSENS (thermal sensor device) on some devices can
      be part of GCC and hence the TSENS properties can also be part
      of the GCC/clock-controller node.
      For more details on the TSENS properties please refer
      Documentation/devicetree/bindings/thermal/qcom-tsens.yaml
