* 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-r8a7742" for the R8A7742 SoC.

      - "renesas,etheravb-r8a7743" for the R8A7743 SoC.

      - "renesas,etheravb-r8a7744" for the R8A7744 SoC.

      - "renesas,etheravb-r8a7745" for the R8A7745 SoC.

      - "renesas,etheravb-r8a77470" for the R8A77470 SoC.

      - "renesas,etheravb-r8a7790" for the R8A7790 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-r8a774a1" for the R8A774A1 SoC.

      - "renesas,etheravb-r8a774b1" for the R8A774B1 SoC.

      - "renesas,etheravb-r8a774c0" for the R8A774C0 SoC.

      - "renesas,etheravb-r8a7795" for the R8A7795 SoC.

      - "renesas,etheravb-r8a7796" for the R8A77960 SoC.

      - "renesas,etheravb-r8a77961" for the R8A77961 SoC.

      - "renesas,etheravb-r8a77965" for the R8A77965 SoC.

      - "renesas,etheravb-r8a77970" for the R8A77970 SoC.

      - "renesas,etheravb-r8a77980" for the R8A77980 SoC.

      - "renesas,etheravb-r8a77990" for the R8A77990 SoC.

      - "renesas,etheravb-r8a77995" for the R8A77995 SoC.

      - "renesas,etheravb-rcar-gen3" as a fallback for the above

		R-Car Gen3 and RZ/G2 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.

       The region for the register block is mandatory.

       The region for the stream buffer is optional, as it is only present on

       R-Car Gen2 and RZ/G1 SoCs, and on R-Car H3 (R8A7795), M3-W (R8A77960),

       M3-W+ (R8A77961), and M3-N (R8A77965).

- 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-names: A list of interrupt names.

		   For the R-Car Gen 3 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.

- rx-internal-delay-ps: Internal RX clock delay.

			This property is mandatory and valid only on R-Car Gen3

			and RZ/G2 SoCs.

			Valid values are 0 and 1800.

			A non-zero value is allowed only if phy-mode = "rgmii".

			Zero is not supported on R-Car D3.

- tx-internal-delay-ps: Internal TX clock delay.

			This property is mandatory and valid only on R-Car H3,

			M3-W, M3-W+, M3-N, V3M, and V3H, and RZ/G2M and RZ/G2N.

			Valid values are 0 and 2000.

			A non-zero value is allowed only if phy-mode = "rgmii".

			Zero is not supported on R-Car V3H.
