Subject: ARM: dts: sunxi: bananapi-m2-plus: Enable RGMII RX/TX delay on
 Ethernet PHY
Git-commit: 3914160ffc0bf762d6d605d4b27036b7b89367ea
Patch-mainline: v5.10-rc5
References: git-fixes

The Ethernet PHY on the Bananapi M2+ has 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").

Fixes: 8c7ba536e709 ("ARM: sun8i: bananapi-m2-plus: Enable dwmac-sun8i")
Fixes: 4904337fe34f ("ARM: dts: sunxi: Restore EMAC changes (boards)")
Fixes: aa8fee415f46 ("ARM: dts: sun8i: h3: Split out non-SoC-specific parts of Bananapi M2 Plus")
