-* 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";
-		};
-	};
