+MediaTek Gigabit Ethernet controller
+=========================================
+
+The gigabit ethernet controller can be found on MediaTek SoCs.
+
+* Ethernet controller node
+
+Required properties:
+- compatible: Should be
+	"mediatek,mt2712-eth": for MT2712 SoC
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the MAC interrupts
+- interrupt-names: the name of interrupt in the interrupts property. These are
+	"macirq": For MT2712 SoC

+- clocks: the clock used by the controller
+- clock-names: the names of the clock listed in the clocks property. These are
+	"axi", "apb", "mac_ext", "ptp", "ptp_parent", "ptp_top": For MT2712 SoC
+- mac-address: See ethernet.txt in the same directory
+- power-domains: phandle to the power domain that the ethernet is part of
+- phy-mode: See ethernet.txt file in the same directory.
+- reset-gpio: gpio number for phy reset.
