* 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>;
|

#size-cells = <0x0>;
|
|
reg = <0xe14 0x8>;
|

reg = <0x1>;

|
|
MoCA interface / MAC to MAC example:

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>;
|
|
