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-qcs404"
"qcom,gcc-sdm630"
"qcom,gcc-sdm660"
"qcom,gcc-sdm845"
"qcom,gcc-sm8150"
- 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
- protected-clocks : Protected clock specifier list as per common clock
binding.
For SM8150 only:
- clocks: a list of phandles and clock-specifier pairs,
one for each entry in clock-names.
- clock-names: "bi_tcxo" (required)
"sleep_clk" (optional)
"aud_ref_clock" (optional)
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>;
};
Example of GCC with protected-clocks properties:
clock-controller@100000 {
compatible = "qcom,gcc-sdm845";
reg = <0x100000 0x1f0000>;
#clock-cells = <1>;
#reset-cells = <1>;
#power-domain-cells = <1>;
protected-clocks = <GCC_QSPI_CORE_CLK>,
<GCC_QSPI_CORE_CLK_SRC>,
<GCC_QSPI_CNOC_PERIPH_AHB_CLK>,
<GCC_LPASS_Q6_AXI_CLK>,
<GCC_LPASS_SWAY_CLK>;
};
Example of GCC with clocks
gcc: clock-controller@100000 {
compatible = "qcom,gcc-sm8150";
reg = <0x00100000 0x1f0000>;
#clock-cells = <1>;
#reset-cells = <1>;
#power-domain-cells = <1>;
clock-names = "bi_tcxo",
"sleep_clk";
clocks = <&rpmcc RPM_SMD_XO_CLK_SRC>,
<&sleep_clk>;
};
