你好

是否有办法通过器件树配置 WKUP_CLKOUT0、以便为外部 WiFi 模块而不是25MHz 提供32KHz 时钟？

WiFi M.2接口的当前器件树配置如下：

&sdhci2 {
        boot-ph-all;
        pinctrl-names = "default";
        pinctrl-0 = <&wifi_pins_default>;
        status = "okay";
        vmmc-supply = <&vdd_3v3>;
        mmc-pwrseq = <&wifi_pwrseq>;
        bus-width = <4>;
        non-removable;
        ti,fails-without-test-cd;
        keep-power-in-suspend;
        ti,driver-strength-ohm = <50>;
        max-frequency = <50000000>;
        cap-power-off-card;
   
        #address-cells = <1>;
        #size-cells = <0>;
        wlcore: wlcore@2 {
                compatible = "ti,cc33xx";
                reg = <2>;
                pinctrl-names = "default";
                pinctrl-0 = <&wifi_irq_pins_default>;
                interrupt-parent = <&main_gpio0>;
                interrupts = <71 IRQ_TYPE_EDGE_FALLING>;
        };
};

谢谢
