Subject: ARM: dts: sun8i: a83t: Enable both RGMII RX/TX delay on Ethernet PHY
Git-commit: 57dbe558457bf4042169bc1f334e3b53a8480a1c
Patch-mainline: v5.10-rc5
References: git-fixes
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").
