clk: qcom: Add DT bindings for ipq8074 gcc clock controller

[mirror_ubuntu-bionic-kernel.git] / Documentation / devicetree / bindings / clock / qcom,gcc.txt

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-mdm9615"

- 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>;
	};
