From: Chen-Yu Tsai <w...@csie.org> The Bananapi M3 has an RTL8211E PHY connected to the EMAC using RGMII. The PHY is powered by DCDC1 through SW @ 3.3V.
The board is designed to use 3.3V with RGMII, instead of the standard reduced voltage of 2.5V we see everywhere. DLDO3, which provides the I/O voltages, is raised to match. This patch enables the EMAC and Realtek PHY drivers in the defconfig. The device tree file already has the EMAC enabled.
