From 57dbe558457bf4042169bc1f334e3b53a8480a1c Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Sun, 25 Oct 2020 00:25:11 +0800 Subject: [PATCH] ARM: dts: sun8i: a83t: Enable both RGMII RX/TX delay on Ethernet PHY The Ethernet PHY on the Bananapi M3 and Cubietruck Plus have the RX and TX delays enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins. Fix the phy-mode description to correct 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").
