Subject: [PATCH 4.19 37/91] ARM: dts: sun8i: h3: orangepi-plus2e: Enable RGMII RX/TX delay on Ethernet PHY

From: Chen-Yu Tsai <wens@...e.org>

[ Upstream commit e080ab31a0aa126b0a7e4f67f2b01b371b852c88 ]

The Ethernet PHY on the Orange Pi Plus 2E 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: 4904337fe34f ("ARM: dts: sunxi: Restore EMAC changes (boards)")
Fixes: 7a78ef92cdc5 ("ARM: sun8i: h3: Enable EMAC with external PHY on Orange Pi Plus 2E")
