+* 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 at 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 = <ðphy>;
+ local-mac-address = [00 00 00 00 00 00];
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ ethphy: ethphy at 1 {
+ reg = <1>;
+ };
+ };
+ };
