Qualcomm Turing Clock & Reset Controller Binding
------------------------------------------------
Required properties :
- compatible: shall contain "qcom,qcs404-turingcc".
- reg: shall contain base register location and length.
- clocks: ahb clock for the TuringCC
- #clock-cells: from common clock binding, shall contain 1.
- #reset-cells: from common reset binding, shall contain 1.
Example:
turingcc: clock-controller@800000 {
compatible = "qcom,qcs404-turingcc";
reg = <0x00800000 0x30000>;
clocks = <&gcc GCC_CDSP_CFG_AHB_CLK>;
#clock-cells = <1>;
#reset-cells = <1>;
};
