From 039359948a4b43a1eb2f1ab06b36e33b3a46640f Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 8 Dec 2017 15:31:57 +0800 Subject: ARM: dts: sun8i: a83t: Enable Ethernet on two boards The Cubietruck Plus has a Realtek RTL8211E RGMII PHY tied to the EMAC. The AXP818 PMIC's regulators provide main power and secondary signaling voltages to the PHY. The latter is always on, as it also supplies the pingroup on the SoC, which has other uses. The Bananapi M3 has a Realtek RTL8211E RGMII PHY tied to the EMAC. The AXP818 PMIC's SW regulators provides power to the PHY. This patch enables Ethernet with the EMAC on both these boards by enabling the emac node and setting all the required properties. A proper ethernet alias is added as well.
