i.MX 6DQ Plus simultaneously use PCIe and ENET

I'd like to confirm how to configure PCIe and ENET when both use simuletaneously for i.MX6DQ Plus.

Does it still need external 100MHz clock for PCIe and external 125MHz clcok for RGMII when using both simultaneously?

I refer to the below thread. It is for i.MX6DQ.


However, I found the description below in i.MX 6DQ schematics.

On the DQP processors this onnection is now
optional, the internal Ethernet PLL can be used
to provide the ENET clock reference


If both need external clock, does BSP implement patches for this use case?
