+* Broadcom BCM7xxx Ethernet Controller (GENET)
+
+Required properties:
+- compatible: should contain one of "brcm,genet-v1", "brcm,genet-v2",
+ "brcm,genet-v3", "brcm,genet-v4".
+- reg: address and length of the register set for the device
+- interrupts: must be two cells, the first cell is the general purpose
+ interrupt line, while the second cell is the interrupt for the ring
+ RX and TX queues operating in ring mode
+- phy-mode: see ethernet.txt file in the same directory
+- #address-cells: should be 1
+- #size-cells: should be 1
+
+Optional properties:
+- clocks: When provided, must be two phandles to the functional clocks nodes
+ of the GENET block. The first phandle is the main GENET clock used during
+ normal operation, while the second phandle is the Wake-on-LAN clock.
+- clock-names: When provided, names of the functional clock phandles, first
+ name should be "enet" and second should be "enet-wol".
+
+- phy-handle: See ethernet.txt file in the same directory; used to describe
+ configurations where a PHY (internal or external) is used.
+
+- fixed-link: When the GENET interface is connected to a MoCA hardware block or
+ when operating in a RGMII to RGMII type of connection, or when the MDIO bus is
+ voluntarily disabled, this property should be used to describe the "fixed link".
+ See Documentation/devicetree/bindings/net/fsl-tsec-phy.txt for information on
+ the property specifics
+
+Required child nodes:
+
+- mdio bus node: this node should always be present regarless of the PHY
+ configuration of the GENET instance
+
+MDIO bus node required properties:
+
+- compatible: should contain one of "brcm,genet-mdio-v1", "brcm,genet-mdio-v2"
+ "brcm,genet-mdio-v3", "brcm,genet-mdio-v4", the version has to match the
+ parent node compatible property (e.g: brcm,genet-v4 pairs with
+ brcm,genet-mdio-v4)
+- reg: address and length relative to the parent node base register address
+- #address-cells: address cell for MDIO bus addressing, should be 1
+- #size-cells: size of the cells for MDIO bus addressing, should be 0
+
+Ethernet PHY node properties:
+
+See Documentation/devicetree/bindings/net/phy.txt for the list of required and
+optional properties.

+Internal Gigabit PHY example:
+
+ethernet@f0b60000 {
+ phy-mode = "internal";
+ phy-handle = <&phy1>;
+ mac-address = [ 00 10 18 36 23 1a ];
+ compatible = "brcm,genet-v4";
+ #address-cells = <0x1>;
+ #size-cells = <0x1>;
+ reg = <0xf0b60000 0xfc4c>;
+ interrupts = <0x0 0x14 0x0>, <0x0 0x15 0x0>;
+
+ mdio@e14 {
+ compatible = "brcm,genet-mdio-v4";
+ #address-cells = <0x1>;
+ #size-cells = <0x0>;
+ reg = <0xe14 0x8>;
+
+ phy1: ethernet-phy@1 {
+ max-speed = <1000>;
+ reg = <0x1>;
+ compatible = "brcm,28nm-gphy", "ethernet-phy-ieee802.3-c22";
+ };
+ };
+};
+
+MoCA interface / MAC to MAC example:
+
+ethernet@f0b80000 {
+ phy-mode = "moca";
+ fixed-link = <1 0 1000 0 0>;
+ mac-address = [ 00 10 18 36 24 1a ];
+ compatible = "brcm,genet-v4";
+ #address-cells = <0x1>;
+ #size-cells = <0x1>;
+ reg = <0xf0b80000 0xfc4c>;
+ interrupts = <0x0 0x16 0x0>, <0x0 0x17 0x0>;
+
+ mdio@e14 {

+ #address-cells = <0x1>;
+ #size-cells = <0x0>;
+ reg = <0xe14 0x8>;
+ };
+};
+
+
+External MDIO-connected Gigabit PHY/switch:
+
+ethernet@f0ba0000 {
+ phy-mode = "rgmii";
+ phy-handle = <&phy0>;
+ mac-address = [ 00 10 18 36 26 1a ];
