Subject: [PATCH 5.10 198/243] ARM: dts: sun8i: h3: orangepi-plus: Fix ethernet phy-mode

From: Salvatore Bonaccorso <carnil@...ian.org>

[ Upstream commit b19d3479f25e8a0ff24df0b46c82e50ef0f900dd ]

Commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay
config") sets the RX/TX delay according to the phy-mode property in the
device tree. For the Orange Pi Plus board this is "rgmii", which is the
wrong setting.

Following the example of a900cac3750b ("ARM: dts: sun7i: a20: bananapro:
Fix ethernet phy-mode") the phy-mode is changed to "rgmii-id" which gets
the Ethernet working again on this board.
