From 2cac47eed45547516103a585f8fd2ef337b4b3f5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michal=20Vok=C3=A1=C4=8D?= Date: Tue, 13 Apr 2021 16:45:57 +0200 Subject: [PATCH] ARM: dts: imx6dl-yapp4: Fix RGMII connection to QCA8334 switch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 0e4a4a08cd78efcaddbc2e4c5ed86b5a5cb8a15e upstream. The FEC does not have a PHY so it should not have a phy-handle. It is connected to the switch at RGMII level so we need a fixed-link sub-node on both ends. This was not a problem until the qca8k.c driver was converted to PHYLINK by commit b3591c2a3661 ("net: dsa: qca8k: Switch to PHYLINK instead of PHYLIB"). That commit revealed the FEC configuration was not correct.
