The processor IOs used for MDIO interface are powered by VDDSHV2 (Dual-voltage IO) supply rail (IO supply for IO group 2).
It is recommended to connect an external pullup resistor (close to device) for the MDIO0_MDIO signal.
Before configuring the MDIO interface, refer the advisory i2329 MDIO: MDIO interface corruption (CPSW and PRU-ICSS) of the device-specific silicon errata.
