Qualcomm Global Clock & Reset Controller Binding

Required properties :

  • compatible : shall contain only one of the following:

          "qcom,gcc-apq8064"
          "qcom,gcc-apq8084"
          "qcom,gcc-ipq8064"
          "qcom,gcc-ipq4019"
          "qcom,gcc-ipq8074"
          "qcom,gcc-msm8660"
          "qcom,gcc-msm8916"
          "qcom,gcc-msm8960"
          "qcom,gcc-msm8974"
          "qcom,gcc-msm8974pro"
          "qcom,gcc-msm8974pro-ac"
          "qcom,gcc-msm8994"
          "qcom,gcc-msm8996"
          "qcom,gcc-msm8998"
          "qcom,gcc-mdm9615"
          "qcom,gcc-sdm845"
    
  • reg : shall contain base register location and length

  • #clock-cells : shall contain 1

  • #reset-cells : shall contain 1

Optional properties :

  • #power-domain-cells : shall contain 1
  • 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.txt

Example:
clock-controller@900000 {
compatible = “qcom,gcc-msm8960”;
reg = <0x900000 0x4000>;
#clock-cells = <1>;
#reset-cells = <1>;
#power-domain-cells = <1>;
};

Example of GCC with TSENS properties:
clock-controller@900000 {
compatible = “qcom,gcc-apq8064”;
reg = <0x00900000 0x4000>;
nvmem-cells = <&tsens_calib>, <&tsens_backup>;
nvmem-cell-names = “calib”, “calib_backup”;
#clock-cells = <1>;
#reset-cells = <1>;
#thermal-sensor-cells = <1>;
};
