* Renesas Electronics Ethernet AVB

This file provides information on what the device node for the Ethernet AVB
interface contains.

Required properties:
- compatible: "renesas,etheravb-r8a7790" if the device is a part of R8A7790 SoC.
	      "renesas,etheravb-r8a7794" if the device is a part of R8A7794 SoC.
- reg: offset and length of (1) the register block and (2) the stream buffer.
- interrupts: interrupt specifier for the sole interrupt.
- phy-mode: see ethernet.txt file in the same directory.
- phy-handle: see ethernet.txt file in the same directory.
- #address-cells: number of address cells for the MDIO bus, must be equal to 1.
- #size-cells: number of size cells on the MDIO bus, must be equal to 0.
- clocks: clock phandle and specifier pair.
- pinctrl-0: phandle, referring to a default pin configuration node.

Optional properties:
- interrupt-parent: the phandle for the interrupt controller that services
		    interrupts for this device.
- pinctrl-names: pin configuration state name ("default").
- renesas,no-ether-link: boolean, specify when a board does not provide a proper
			 AVB_LINK signal.
- renesas,ether-link-active-low: boolean, specify when the AVB_LINK signal is
				 active-low instead of normal active-high.

Example:

	ethernet@e6800000 {
		compatible = "renesas,etheravb-r8a7790";
		reg = <0 0xe6800000 0 0x800>, <0 0xee0e8000 0 0x4000>;
		interrupt-parent = <&gic>;
		interrupts = <0 163 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&mstp8_clks R8A7790_CLK_ETHERAVB>;
		phy-mode = "rmii";
		phy-handle = <&phy0>;
		pinctrl-0 = <&ether_pins>;
		pinctrl-names = "default";
		renesas,no-ether-link;
		#address-cells = <1>;
		#size-cells = <0>;

		phy0: ethernet-phy@0 {
			reg = <0>;
			interrupt-parent = <&gpio2>;
			interrupts = <15 IRQ_TYPE_LEVEL_LOW>;
		};
	};
