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>; }; |
