    This looks suspiciously like what we have the common clock bindings for:

    refclk {
    compatible = "fixed-clock";
    #clock-cells = <0>;
    clock-frequency = <19200000>;
    }

    wilink {
    compatible = "ti,wilink7";
    interrupt-parent = <&some_interrupt_controller>;
    interrupts = <0 1 1>;
    clocks = <&refclk>, <&refclk>;
    clock-names = "refclk", "txoclk";
    };

    Could you not use them?

    Thanks,
    Mark.
