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.

Fixes: 95c3b0635ea4 ("sunxi: dts: arm64: update devicetree files from Linux-v6.6-rc6") Signed-off-by: Chukun Pan amadeus@jmu.edu.cn Reviewed-by: Jernej Skrabec jernej.skrabec@gmail.com --- Hi,

this is a port of the corresponding Linux patch, that fixes Ethernet on that board. The patch is in Linux' sunxi/fixes-for-6.7 queue, awaiting a merge anytime soon. For me this indeed fixes Ethernet operation in U-Boot on that board.

Cheers, Andre
