  27 - reg : shall contain base register location and length
  28 - #clock-cells : shall contain 1
  29 - #reset-cells : shall contain 1
  30
  31 Optional properties :
  32 - #power-domain-cells : shall contain 1
  33 - Qualcomm TSENS (thermal sensor device) on some devices can
  34 be part of GCC and hence the TSENS properties can also be
  35 part of the GCC/clock-controller node.
  36 For more details on the TSENS properties please refer
  37 Documentation/devicetree/bindings/thermal/qcom-tsens.txt

  39 Example:
  40         clock-controller@900000 {
  41                 compatible = "qcom,gcc-msm8960";
  42                 reg = <0x900000 0x4000>;
  43                 #clock-cells = <1>;
  44                 #reset-cells = <1>;
  45                 #power-domain-cells = <1>;
  46         };
  47
  48 Example of GCC with TSENS properties:
  49         clock-controller@900000 {
  50                 compatible = "qcom,gcc-apq8064";
  51                 reg = <0x00900000 0x4000>;
  52                 nvmem-cells = <&tsens_calib>, <&tsens_backup>;
  53                 nvmem-cell-names = "calib", "calib_backup";
  54                 #clock-cells = <1>;
  55                 #reset-cells = <1>;
  56                 #thermal-sensor-cells = <1>;
  57         };
