+Subject: [PATCH] arm64: dts: allwinner: h616: update emac for Orange Pi Zero 3
+
+The current emac setting is not suitable for Orange Pi Zero 3,
+move it back to Orange Pi Zero 2 DT. Also update phy mode and
+delay values for emac on Orange Pi Zero 3.
+With these changes, Ethernet now looks stable.
