From 82ea7c7fb4e90620beba8b6436fc12df2379ef8d Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Mon, 10 Oct 2022 16:52:25 +0200 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.
