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>;
};
};
Regards.
