OrangePi's aren't the only units that use emac1. I suggest you isolate the patch work so that it is easier to work with. OrangePi DTS specific changes should have its own patch, as should the driver(s) and H616 DTSI.

yeah, that will be good to apply this patch just for zero2w, will take a look at other pr to figure out how to do that. thanks for your tip.
