第一步：打开电源

路径：kernelarcharm64bootdtsrockchiprk3568-evb1-ddr4-v10.dtsi

      pcie30_avdd0v9: pcie30-avdd0v9 {
            compatible = "regulator-fixed";
            regulator-name = "pcie30_avdd0v9";
            regulator-always-on;
            regulator-boot-on;
            regulator-min-microvolt = <900000>;
            regulator-max-microvolt = <900000>;
            vin-supply = <&vcc3v3_sys>;
      };

      pcie30_avdd1v8: pcie30-avdd1v8 {
            compatible = "regulator-fixed";
            regulator-name = "pcie30_avdd1v8";
            regulator-always-on;
            regulator-boot-on;
            regulator-min-microvolt = <1800000>;
            regulator-max-microvolt = <1800000>;
            vin-supply = <&vcc3v3_sys>;
      };

      vcc3v3_pcie: gpio-regulator {
            compatible = "regulator-fixed";
            regulator-name = "vcc3v3_pcie";
            regulator-min-microvolt = <3300000>;
            regulator-max-microvolt = <3300000>;
            enable-active-high;
            gpio = <&gpio0 RK_PD4 GPIO_ACTIVE_LOW>; //控制电源引脚
            startup-delay-us = <5000>;
            vin-supply = <&dc_12v>;
            regulator-always-on;
            regulator-boot-on;
      };

      vcc3v3_bu: vcc3v3-bu {
            compatible = "regulator-fixed";
            regulator-name = "vcc3v3_bu";
            regulator-always-on;
            regulator-boot-on;
            regulator-min-microvolt = <3300000>;
            regulator-max-microvolt = <3300000>;
            vin-supply = <&vcc5v0_sys>;
      };
第二步：打开DTS节点

路径：kernelarcharm64bootdtsrockchiprk3568-evb1-ddr4-v10.dtsi；

&pcie30phy {
      status = "okay";
};
第三步：查看设备节点是否生成（插入M.2固态硬盘）
