+Subject: [PATCH 731/768] dt-bindings: net: dsa: lantiq_gswip: Add missing
+ phy-mode and fixed-link
+
+The CPU port has to specify a phy-mode and either a phy or a fixed-link.
+Since GSWIP is connected using a SoC internal protocol there's no PHY
+involved. Add phy-mode = "internal" and a fixed-link to describe the
+communication between the PMAC (Ethernet controller) and GSWIP switch.
