Subject: [PATCH net-next v2 01/12] dt-bindings: net: dsa: lantiq_gswip: Add missing CPU port phy-mode and fixed-link to example

From: Martin Blumenstingl <martin.blumenstingl@...glemail.com>

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 the example code
to describe the communication between the PMAC (Ethernet controller) and
GSWIP switch.
