Example Device Tree Configuration for Ethernet with RMII mode with Reference Clock (STM32MP15).

[Gencay]

I have the connection on the image from AN5031 for my custom board and I my clock configuration can be seen on the other picture. Is my clock configuration correct and how its device tree code should be?
