WebThe ADIN PHY driver instantiates via Linux's phylib framework, which is typically enabled on most systems. Depending on the MAC driver that is used and the operating mode (MII, RGMII, RMII), a device-tree entry for the PHY may or may-not be needed. The PHY can be configured via HW pins (see datasheet), or via SW. Optional properties (for MAC): WebOne refers to support from the device tree while the other is contained in the Linux kernel driver.
