This is a regression, right? The addition of that patch has caused previously working boards to stop working, correct? That means it needs to be reverted. We also need to get out of our heads the idea that LAN8710A is somehow special in needing this. It isn't. Thus, there should be no special flags to "work around" this "problem". -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
