-* 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-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-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.
