Your reasoning does not make sense. The ap80x.dtsi file does not specify "marvell,xenon-phy-slow-mode". It is not specified at this level. It is already specified at board level. Given that Macchiatobin will still use slow mode, why remove the marvell,xenon-phy-slow-mode property from this file? Also, if you're upgrading ap80x.dtsi to use a bus-width of 8, why keep the bus-width specifier of 8 in the board files? This patch just doesn't make sense, and your responses to our points seem to add to the confusion. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
