The Nanopi M1 Plus uses an external Realtek RTL8211E PHY in RGMII mode, enabled by a GPIO-based regulator. Signed-off-by: Luis Araneda <redacted> --- Changes v2 -> v3: - Changed PHY address from broadcast to board specific Changes v1 -> v2: - Removed unnecessary property - Corrected part address to match reg value arch/arm/boot/dts/sun8i-h3-nanopi-m1-plus.dts | 30 +++++++++++++++++++++++++++ 1 file changed, 30 insertions(+)
