From ec527314d054465403ac41c1821c893f354b9936 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Sat, 25 Jul 2020 00:42:21 +0300 Subject: [PATCH] ARM: dts: keystone-k2g-evm: fix rgmii phy-mode for ksz9031 phy Since commit 7d105884856a ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on keystone-k2g-evm board. The above board have phy-mode = "rgmii-id" and it is worked before because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay by default. After above commit, the KSZ9031 PHY starts handling phy mode properly and enables both RX and TX delays, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.
