We currently developing a board with (i.MX8QXP + DDR3L16bit) and running Linux (L4.14.98_2.0.0).
We plan to replace i.MX8QXP with i.MX8DX in the future, so we are starting software porting for i.MX8DX.
The following content is recognized as a change point from i.MX8QXP to i.MX8DX.
1) u-boot: Change USB3.0 to USB2.0
CONFIG_USB_XHCI_HCD = n
CONFIG_USB_XHCI_IMX8 = n
2) device tree: GPU Clock down
& gpu_3d0 {
-assigned-clock-rates = <700000000>, <850000000>;
+ assigned-clock-rates = <372000000>, <372000000>;
Besides this, Ether is also changed to 1G-> 100M. Do we need to modify the device tree for this?
If so, how should it be corrected?
If there are other points that need to be corrected, please let me know.

Kanou
