[PATCH] arm64: imx8mp: Auto-detect PHY on i.MX8MP DHCOM

[sbabic at denx.de]

> The i.MX8MP DHCOM SoM may be populated with either KSZ9131RNXI RGMII PHY
> or LAN8740Ai RMII PHY attached to EQoS MAC, and either external RGMII PHY
> or LAN8740Ai RMII PHY attached to FEC MAC. The SoM configuration can be
> detected for each MAC by reading RX_CTL pull resistor state early on boot.
> Make use of this, detect the exact PHY configuration, and patch control DT
> accordingly so that the ethernet is configured correctly in U-Boot.
