From a900cac3750b9f0b8f5ed0503d9c6359532f644d Mon Sep 17 00:00:00 2001 From: Hermann Lauer Date: Thu, 28 Jan 2021 12:18:42 +0100 Subject: [PATCH] ARM: dts: sun7i: a20: bananapro: Fix ethernet phy-mode BPi Pro needs TX and RX delay for Gbit to work reliable and avoid high packet loss rates. The realtek phy driver overrides the settings of the pull ups for the delays, so fix this for BananaPro. Fix the phy-mode description to correctly reflect this so that the implementation doesn't reconfigure the delays incorrectly. This happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config").
