你好:

我使用07版本的BSP,然需要RTS自动切换,然后我在设备树添加了下面的属性rts-gpios,虽然确实是可以自动切换,但是执行休眠唤醒指令后,发现不能唤醒,去掉这个属性是可以休眠唤醒的,下面是我的设备树配置

&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins>;
status = "okay";
rts-gpios = <&gpio3 4 GPIO_ACTIVE_HIGH>;
rs485-rts-active-high;
rs485-rx-during-tx;
rs485-rts-delay = <1 1>;
linux,rs485-enabled-at-boot-time;
};

 请问如何让系统在添加rts属性后可以休眠唤醒?
