Hi,

I currently have a project with a Toradex Colibri IMX8X SOM board
whith an onboard Micrel KSZ8041NL Ethernet PHY.

The hardware is described in the devictree properly so I expected that
the onboard Ethernet with the phy is working.

Currently I'm not able to get the link up.

I already compared it to the BSP kernel, but I didn't found anything
helpful. The BSP kernel is working.

Do you know if there is something in the kernel missing and got it running?

Yes, you may just revert the following commit babfaa9556d7 ("clk: imx: scu:
add more scu clocks")

Alternatively, just commenting out the following single line also helps:

I just found this out about two weeks ago before I went to vacation and since
have to find out with NXP what exactly the idea of this clocking/SCFW stuff is
related to our hardware.

@NXP: If any of you guys could shed some light that would be much
appreciated. Thanks!
