It is working by default hardware settings, but I agree we should do it in dts,
I found it has a lot of dependency if we want to enable the gpio reset for FEC1,
many gpio reset patch missed in upstream kernel, need patch work for MAX7322 first, so
I plan to remove FEC support in this patch set, and will upstream the MAX7322
reset patch first, then will add FEC support after MAX7322 patch done. Will send
out V3 patch to drop fec support for now, thanks.

Anson.
