-* 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/fixed-link.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 {
- compatible = "brcm,genet-mdio-v4";
- #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 ];
- compatible = "brcm,genet-v4";
- #address-cells = <0x1>;
- #size-cells = <0x1>;
- reg = <0xf0ba0000 0xfc4c>;
- interrupts = <0x0 0x18 0x0>, <0x0 0x19 0x0>;
-
- mdio@0e14 {
- compatible = "brcm,genet-mdio-v4";
- #address-cells = <0x1>;
- #size-cells = <0x0>;
- reg = <0xe14 0x8>;
-
- phy0: ethernet-phy@0 {
- max-speed = <1000>;
- reg = <0x0>;
- compatible = "brcm,bcm53125", "ethernet-phy-ieee802.3-c22";
