From 041dd8e9c4be5bcb49845955e4c472d0c2c46e1e Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 17 Jun 2020 14:33:16 -0300 Subject: [PATCH] ARM: dts: imx6qdl-sabresd: Fix AR8031 phy-mode As per kernel commit 0672d22a1924 ("ARM: dts: imx: Fix the AR803X phy-mode) the correct phy-mode should be "rgmii-id", so fix it accordingly to fix the Ethernet regression. This problem has been exposed by commit: commit 13114f38e2ccea9386726d8b9831dfc310589548 Author: Vladimir Oltean Date: Thu May 7 00:11:51 2020 +0200 phy: atheros: Explicitly disable RGMII delays To eliminate any doubts about the out-of-reset value of the PHY, that the driver previously relied on. If bisecting shows that this commit breaks your board you probably have a wrong PHY interface mode. You probably want the PHY_INTERFACE_MODE_RGMII_RXID or PHY_INTERFACE_MODE_RGMII_ID mode.
