请教D1-H J2引脚 REFCLK-OUT没有时钟信号输出的问题

[Apollo5520]

如上图，想用这个来给xr829提供时钟信号，用示波器测不到有信号输出

		wlan: wlan@0 {
			compatible    = "allwinner,sunxi-wlan";
			clock-names = "32k-fanout1", "osc24m", "fanout-24m";
			clocks = <&ccu CLK_FANOUT1_OUT>, <&dcxo24M>, <&ccu CLK_FANOUT_24M>;
			wlan_busnum    = <0x1>;
			wlan_regon    = <&pio PG 12 GPIO_ACTIVE_HIGH>;
			wlan_hostwake  = <&pio PG 10 GPIO_ACTIVE_HIGH>;
			/*wlan_power    = "VCC-3V3";*/
			/*wlan_power_vol = <3300000>;*/
			/*interrupt-parent = <&pio>;
			interrupts = < PG 10 IRQ_TYPE_LEVEL_HIGH>;*/
			wakeup-source;

		};

dts配置成上面的了
有哪位兄弟知道是什么原因吗？谢谢
