PHY 在 Linux 系统上运行所需的两个基本元件是器件树和驱动程序文件，DP83869HM 驱动程序可在此处找到。以下是器件树外观的示例格式。可在以下路径下的任何开源内核上找到该示例：root/Documentation/devicetree/bindings/net/ti。

 #include <dt-bindings/net/ti-dp83869.h>
    mdio0 {
      #address-cells = <1>;
      #size-cells = <0>;
      ethphy0: ethernet-phy@0 {
        reg = <0>;
        tx-fifo-depth = <DP83869_PHYCR_FIFO_DEPTH_4_B_NIB>;
        rx-fifo-depth = <DP83869_PHYCR_FIFO_DEPTH_4_B_NIB>;
        ti,op-mode = <DP83869_RGMII_COPPER_ETHERNET>;
        ti,max-output-impedance;
        ti,clk-output-sel = <DP83869_CLK_O_SEL_CHN_A_RCLK>;
        rx-internal-delay-ps = <2000>;
        tx-internal-delay-ps = <2000>;
      };
    };
