Some suggestions you could try:

- Try to use phy-mode = "rgmii-id"; instead,
- The PHY address 0 does not match the reg value of 4, so you need to
double check the PHY address and make the @ and reg values to match.
- If you have a GPIO connected to the Ethernet PHY reset pin, then you
should describe it in the dts and also provide a delay as per the
AR803X datasheet.
