+* 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-pro4-ave4" : for Pro4 SoC
+       - "socionext,uniphier-pxs2-ave4" : for PXs2 SoC
+       - "socionext,uniphier-ld20-ave4" : for LD20 SoC
+       - "socionext,uniphier-ld11-ave4" : for LD11 SoC
+ - reg: Address where registers are mapped and size of region.
+ - interrupts: Should contain the MAC interrupt.
+ - phy-mode: See ethernet.txt in the same directory. Allow to choose
+       "rgmii", "rmii", or "mii" according to the PHY.
+ - pinctrl-names: List of assigned state names, see pinctrl
+       binding documentation.
+ - pinctrl-0: List of phandles to configure the GPIO pin,
+       see pinctrl binding documentation. Choose this appropriately
+       according to phy-mode.
+       - <&pinctrl_ether_rgmii> if phy-mode is "rgmii".
+       - <&pinctrl_ether_rmii> if phy-mode is "rmii".
+       - <&pinctrl_ether_mii> if phy-mode is "mii".
+ - phy-handle: Should point to the external phy device.
+       See ethernet.txt file in the same directory.
+ - mdio subnode: Should be device tree subnode with the following required
+       properties:
+       - #address-cells: Must be <1>.
+       - #size-cells: Must be <0>.
+       - reg: phy ID number, usually a small integer.
+
+Optional properties:
+ - local-mac-address: See ethernet.txt in the same directory.
+
+Example:
+
+       ether: ethernet@65000000 {
+               compatible = "socionext,uniphier-ld20-ave4";
+               reg = <0x65000000 0x8500>;
+               interrupts = <0 66 4>;
+               pinctrl-names = "default";
+               pinctrl-0 = <&pinctrl_ether_rgmii>;
+               phy-mode = "rgmii";
+               phy-handle = <&ethphy>;
+               local-mac-address = [00 00 00 00 00 00];
+               mdio {
+                       #address-cells = <1>;
+                       #size-cells = <0>;
+                       ethphy: ethphy@1 {
+                               reg = <1>;
+                       };
+               };
+       };
