* Renesas Electronics SH EtherMAC



This file provides information on what the device node for the SH EtherMAC

interface contains.



Required properties:

- compatible: Must contain one or more of the following:

	      "renesas,gether-r8a7740" if the device is a part of R8A7740 SoC.

	      "renesas,ether-r8a7743"  if the device is a part of R8A7743 SoC.

	      "renesas,ether-r8a7745"  if the device is a part of R8A7745 SoC.

	      "renesas,ether-r8a7778"  if the device is a part of R8A7778 SoC.

	      "renesas,ether-r8a7779"  if the device is a part of R8A7779 SoC.

	      "renesas,ether-r8a7790"  if the device is a part of R8A7790 SoC.

	      "renesas,ether-r8a7791"  if the device is a part of R8A7791 SoC.

	      "renesas,ether-r8a7793"  if the device is a part of R8A7793 SoC.

	      "renesas,ether-r8a7794"  if the device is a part of R8A7794 SoC.

	      "renesas,gether-r8a77980" if the device is a part of R8A77980 SoC.

	      "renesas,ether-r7s72100" if the device is a part of R7S72100 SoC.

	      "renesas,ether-r7s9210" if the device is a part of R7S9210 SoC.

	      "renesas,rcar-gen1-ether" for a generic R-Car Gen1 device.

	      "renesas,rcar-gen2-ether" for a generic R-Car Gen2 or RZ/G1

	                                device.



	      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 E-DMAC/feLic register block (required),

       (2) the TSU register block (optional).

- 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:

- pinctrl-names: pin configuration state name ("default").

- renesas,no-ether-link: boolean, specify when a board does not provide a proper

			 Ether LINK signal.

- renesas,ether-link-active-low: boolean, specify when the Ether LINK signal is

				 active-low instead of normal active-high.



Example (Lager board):



	ethernet@ee700000 {

		compatible = "renesas,ether-r8a7790",

		             "renesas,rcar-gen2-ether";

		reg = <0 0xee700000 0 0x400>;

		interrupt-parent = <&gic>;

		interrupts = <0 162 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&mstp8_clks R8A7790_CLK_ETHER>;

		phy-mode = "rmii";

		phy-handle = <&phy1>;

		pinctrl-0 = <&ether_pins>;

		pinctrl-names = "default";

		renesas,ether-link-active-low;

		#address-cells = <1>;

		#size-cells = <0>;



		phy1: ethernet-phy@1 {

			reg = <1>;

			interrupt-parent = <&irqc0>;

			interrupts = <0 IRQ_TYPE_LEVEL_LOW>;

			pinctrl-0 = <&phy1_pins>;

			pinctrl-names = "default";

		};

	};
