Subject: [PATCH v3] ARM: dts: sun7i: a20: bananapro: Fix ethernet phy-mode
Date: Thu, 28 Jan 2021 10:40:41 +0100 [thread overview]
Message-ID: <20210128094040.GD11559@lemon.iwr.uni-heidelberg.de> (raw)
In-Reply-To: <20210121170836.GA4948@lemon.iwr.uni-heidelberg.de>
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.
Fixes: 10662a33dcd9 ("ARM: dts: sun7i: Add dts file for Bananapro board")
