Boot lockup on imx8mp in llinux-next

[Alexander Stein]

Hello everyone,

I noticed that my imx8mp based board (TQMa8MPxL, not yet mainline) locked up 
during boot in linux-next. I bisected it down to commit [1].
I found out that disabling 'fec' and 'eqos' (both ethernet controller) nodes 
in DT resulted in booting Kernel, alas NFS boot failed eventually obviously. 
Reverting make things working again.
I have no idea which clock is the actual culprit here and how to fix it. I 
just wanted to make you aware of this issue.

Best regards,
Alexander
