* Renesas Electronics Ethernet AVB

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

Required properties:
- compatible: Must contain one or more of the following:
      - "renesas,etheravb-r8a7743" for the R8A7743 SoC.
      - "renesas,etheravb-r8a7745" for the R8A7745 SoC.
      - "renesas,etheravb-r8a7790" for the R8A7790 SoC.
      - "renesas,etheravb-r8a7791" for the R8A7791 SoC.
      - "renesas,etheravb-r8a7792" for the R8A7792 SoC.
      - "renesas,etheravb-r8a7793" for the R8A7793 SoC.
      - "renesas,etheravb-r8a7794" for the R8A7794 SoC.
      - "renesas,etheravb-rcar-gen2" as a fallback for the above
		R-Car Gen2 and RZ/G1 devices.

      - "renesas,etheravb-r8a7795" for the R8A7795 SoC.
      - "renesas,etheravb-r8a7796" for the R8A7796 SoC.
      - "renesas,etheravb-rcar-gen3" as a fallback for the above
		R-Car Gen3 devices.

	When compatible with the generic version, nodes must list the
	SoC-specific version corresponding to the platform first followed by
	the generic version.

- reg: offset and length of (1) the register block and (2) the stream buffer.
- interrupts: A list of interrupt-specifiers, one for each entry in
	      interrupt-names.
	      If interrupt-names is not present, an interrupt specifier
	      for a single muxed 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.
- interrupt-names: A list of interrupt names.
		   For the R8A779[56] SoCs this property is mandatory;
		   it should include one entry per channel, named "ch%u",
		   where %u is the channel number ranging from 0 to 24.
		   For other SoCs this property is optional; if present
		   it should contain "mux" for a single muxed interrupt.
- 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.
