+* Socionext AVE ethernet controller
+
+This describes the devicetree bindings for AVE ethernet controller
+implemented on Socionext UniPhier SoCs.
+
+Required properties:
+ - compatible:  Should be "socionext,uniphier-ave4"
+ - reg: Address where registers are mapped and size of region.
+ - interrupts: IRQ common for mac and phy interrupts.
+ - phy-mode: See ethernet.txt in the same directory.
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+ - Node, with 'reg' property, for each PHY on the MDIO bus.
+
+Optional properties:
+ - socionext,desc-bits: 32/64 descriptor size. Default 32.
+ - local-mac-address: See ethernet.txt in the same directory.
+ - pinctrl-names: List of assigned state names, see pinctrl
+	binding documentation.
+ - pinctrl-0: List of phandles to configure the GPIO pin used
+	as interrupt line, see also generic and your platform
+	specific pinctrl binding documentation.
+ - socionext,internal-phy-interrupt: Boolean to denote if the
+	PHY interrupt is internally handled by the MAC.
+
+
+Example:
+
+	eth: ethernet@65000000 {
+		compatible = "socionext,uniphier-ave4";
+		reg = <0x65000000 0x8500>;
+		interrupts = <0 66 4>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&pinctrl_ether_rgmii>;
+		phy-mode = "rgmii";
+		socionext,desc-bits = <64>;
+		local-mac-address = [00 00 00 00 00 00];
+
+		#address-cells = <1>;
+		#size-cells = <0>;
+		ethphy: ethphy@1 {
+			reg = <1>;
+		};
+	};
