From 37685f6a63eeca2135d1f704e7638409a071b1f6 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 19 Feb 2019 08:46:33 -0800 Subject: [PATCH] ARM: dts: am335x-evm: Fix PHY mode for ethernet The PHY must add both tx and rx delay and not only on the tx clock. The board uses AR8031_AL1A PHY where the rx delay is enabled by default, the tx dealy is disabled. The reason why rgmii-txid worked because the rx delay was not disabled by the driver so essentially we ended up with rgmii-id PHY mode.
