Subject: [PATCH v2] ARM: dts: sun7i: a20: bananapro: Fix ethernet node
Date: Thu, 21 Jan 2021 18:08:36 +0100	[thread overview]
Message-ID: <20210121170836.GA4948@lemon.iwr.uni-heidelberg.de> (raw)

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 Banana Pro.
