+examples:

+          port@6 {
+            reg = <6>;
+            label = "lan5";
+            phy-mode = "internal";
+            phy-handle = <&t1phy4>;
+          };
+          port@7 {
+            reg = <7>;
+            label = "lan3";
+            phy-mode = "internal";
+            phy-handle = <&t1phy5>;
+          };
+        };
+
+        mdio {

..

+          t1phy4: ethernet-phy@6{
+            reg = <0x6>;
+          };
+          t1phy5: ethernet-phy@7{
+            reg = <0x7>;
+          };

I know it is only an example, but the numbering is a little odd here.

Port 6, which is named lan5 using t1phy4 at address 6?

I would be more likely to use t1phy6 instead of t1phy4. And t1phy7
instead of t1phy5.
