ADIS16465外部时钟模式的设备树配置

我想将ADIS16465设置为scaled sync mode,这需要在设备树中配置相关的时钟节点,官方例程只给出了一个标签,如下所示,clocks参数只给出了一个标签,但是并不知道具体在怎么配置这个标签,具体需要声明哪些参数呢?

imu@0 {
		compatible = "adi,adis16495-1";
		reg = <0>;
		spi-max-frequency = <3200000>;
		spi-cpol;
		spi-cpha;
		interrupts = <25 IRQF_TRIGGER_FALLING>;
		interrupt-parent = <&gpio>;
		interrupt-names = "DIO2";
		clocks = <&adis16495_sync>;
		clock-names = "sync";
		adi,ext-clk-pin = "DIO1";
       };
