Subject: [PATCH 5.4 001/453] ARM: dts: sun7i: bananapi: Enable RGMII RX/TX delay on Ethernet PHY

From: Pablo Greco <pgreco@...tosproject.org>

[ Upstream commit 8c9cb4094ccf242eddd140efba13872c55f68a87 ]

The Ethernet PHY on the Bananapi M1 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").
