+* 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 at 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 at 1 {
+ reg = <1>;
+ };
+ };
