Subject: [PATCH 4.19 023/220] ARM: dts: sun8i: h3: bpi-m2-plus: Fix address for external RGMII Ethernet PHY

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

[ Upstream commit db9fd9d13e30fc67737ac9893a82e6b095e85a64 ]

The external RTL8211E RGMII Ethernet PHY is configured via external
resistors to use the address 0x1. The 0x0 address is a broadcast address
for this family of PHYs, and should not be used explicitly.

Fixes: 8c7ba536e709 ("ARM: sun8i: bananapi-m2-plus: Enable dwmac-sun8i")
Fixes: 4904337fe34f ("ARM: dts: sunxi: Restore EMAC changes (boards)")
