* 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-ld11-ave4" : for LD11 SoC
	- "socionext,uniphier-ld20-ave4" : for LD20 SoC
	- "socionext,uniphier-pxs3-ave4" : for PXs3 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", "mii", or "internal" according to the PHY.
	The acceptable mode is SoC-dependent.
 - phy-handle: Should point to the external phy device.
	See ethernet.txt file in the same directory.
 - clocks: A phandle to the clock for the MAC.
	For Pro4 SoC, that is "socionext,uniphier-pro4-ave4",
	another MAC clock, GIO bus clock and PHY clock are also required.
 - clock-names: Should contain
	- "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC
	- "ether" for others
 - resets: A phandle to the reset control for the MAC. For Pro4 SoC,
	GIO bus reset is also required.
 - reset-names: Should contain
	- "ether", "gio" for Pro4 SoC
	- "ether" for others
 - socionext,syscon-phy-mode: A phandle to syscon with one argument
	that configures phy mode. The argument is the ID of MAC instance.

Optional properties:
 - local-mac-address: See ethernet.txt in the same directory.

Required subnode:
 - mdio: A container for child nodes representing phy nodes.
         See phy.txt in the same directory.

Example:

	ether: ethernet@65000000 {
		compatible = "socionext,uniphier-ld20-ave4";
		reg = <0x65000000 0x8500>;
		interrupts = <0 66 4>;
		phy-mode = "rgmii";
		phy-handle = <&ethphy>;
		clock-names = "ether";
		clocks = <&sys_clk 6>;
		reset-names = "ether";
		resets = <&sys_rst 6>;
		socionext,syscon-phy-mode = <&soc_glue 0>;
		local-mac-address = [00 00 00 00 00 00];

		mdio {
			#address-cells = <1>;
			#size-cells = <0>;

			ethphy: ethphy@1 {
				reg = <1>;
			};
		};
	};
