In fact, the evb-rk3229 is default supported the integrated phy,
not need to change any hardware. So it is better to enbale it and
disable external 1000M phy.

Where is "ethernet-phy-id1234.d400" defined/used? I don't see anything
in Linux or U-Boot.
Yes, The "ethernet-phy-id1234.d400" is not defined at linux/U-Boot.
It does use the "ethernet-phy-ieee802.3-c22". The
"ethernet-phy-id1234.d400" is a decorated aliases, the 0x1234d0 is the
phy-id.

Documentation in the documentation for DTS bindings?
Shouldn't this be rockchip,phy-is-integrated?
What is the status of this on the Linux side?
I think it's consistent with kernel, especially if we might use kernel
DTB file.
