And the corresponding DT will be along these lines:

	clocks {
		ranges;
		#address-cells = <1>;
		#size-cells = <1>;

		xtal: xtal {
			compatible = "fixed-clock";
			clock-frequency = <27000000>;
			#clock-cells = <0>;
		};

		clkgen: clkgen@10000 {
			compatible = "sigma,tango4-clkgen";
			reg = <0x10000 0x30>;
			clocks = <&xtal>;
			clock-output-names = "cpuclk", "sysclk";
			#clock-cells = <1>;
		};

		periphclk: periphclk {
			compatible = "fixed-factor-clock";
			clocks = <&clkgen 0>;
			clock-mult = <1>;
			clock-div  = <2>;
			#clock-cells = <0>;
		};
	};
