1 * Broadcom BCM7xxx Ethernet Controller (GENET)
4 - compatible: should contain one of "brcm,genet-v1", "brcm,genet-v2",
5 "brcm,genet-v3", "brcm,genet-v4", "brcm,genet-v5", "brcm,bcm2711-genet-v5" or
6 "brcm,bcm7712-genet-v5".
7 - reg: address and length of the register set for the device
8 - interrupts and/or interrupts-extended: must be two cells, the first cell
9 is the general purpose interrupt line, while the second cell is the
10 interrupt for the ring RX and TX queues operating in ring mode. An
11 optional third interrupt cell for Wake-on-LAN can be specified.
12 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
13 for information on the property specifics.
14 - phy-mode: see ethernet.txt file in the same directory
15 - #address-cells: should be 1
16 - #size-cells: should be 1
19 - clocks: When provided, must be two phandles to the functional clocks nodes
20 of the GENET block. The first phandle is the main GENET clock used during
21 normal operation, while the second phandle is the Wake-on-LAN clock.
22 - clock-names: When provided, names of the functional clock phandles, first
23 name should be "enet" and second should be "enet-wol".
25 - phy-handle: See ethernet.txt file in the same directory; used to describe
26 configurations where a PHY (internal or external) is used.
28 - fixed-link: When the GENET interface is connected to a MoCA hardware block or
29 when operating in a RGMII to RGMII type of connection, or when the MDIO bus is
30 voluntarily disabled, this property should be used to describe the "fixed link".
31 See Documentation/devicetree/bindings/net/fixed-link.txt for information on
32 the property specifics
36 - mdio bus node: this node should always be present regardless of the PHY
37 configuration of the GENET instance
39 MDIO bus node required properties:
41 - compatible: should contain one of "brcm,genet-mdio-v1", "brcm,genet-mdio-v2"
42 "brcm,genet-mdio-v3", "brcm,genet-mdio-v4", "brcm,genet-mdio-v5", the version
43 has to match the parent node compatible property (e.g: brcm,genet-v4 pairs
44 with brcm,genet-mdio-v4)
45 - reg: address and length relative to the parent node base register address
46 - #address-cells: address cell for MDIO bus addressing, should be 1
47 - #size-cells: size of the cells for MDIO bus addressing, should be 0
49 Ethernet PHY node properties:
51 See Documentation/devicetree/bindings/net/phy.txt for the list of required and
