1 | * Broadcom BCM7xxx Ethernet Controller (GENET) |
2 | ||
3 | Required properties: | |
4 | - compatible: should contain one of "brcm,genet-v1", "brcm,genet-v2", | |
0ce5aa1d | 5 | "brcm,genet-v3", "brcm,genet-v4", "brcm,genet-v5". |
aab5127d | 6 | - reg: address and length of the register set for the device |
75835695 DB |
7 | - interrupts and/or interrupts-extended: must be two cells, the first cell |
8 | is the general purpose interrupt line, while the second cell is the | |
9 | interrupt for the ring RX and TX queues operating in ring mode. An | |
10 | optional third interrupt cell for Wake-on-LAN can be specified. | |
11 | See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt | |
12 | for information on the property specifics. | |
e8f08ee0 | 13 | - phy-mode: see ethernet.txt file in the same directory |
9e5f040d FF |
14 | - #address-cells: should be 1 |
15 | - #size-cells: should be 1 | |
aab5127d FF |
16 | |
17 | Optional properties: | |
d94b27c8 FF |
18 | - clocks: When provided, must be two phandles to the functional clocks nodes |
19 | of the GENET block. The first phandle is the main GENET clock used during | |
20 | normal operation, while the second phandle is the Wake-on-LAN clock. | |
21 | - clock-names: When provided, names of the functional clock phandles, first | |
22 | name should be "enet" and second should be "enet-wol". | |
aab5127d | 23 | |
e8f08ee0 SS |
24 | - phy-handle: See ethernet.txt file in the same directory; used to describe |
25 | configurations where a PHY (internal or external) is used. | |
aab5127d FF |
26 | |
27 | - fixed-link: When the GENET interface is connected to a MoCA hardware block or | |
28 | when operating in a RGMII to RGMII type of connection, or when the MDIO bus is | |
29 | voluntarily disabled, this property should be used to describe the "fixed link". | |
ae21888f | 30 | See Documentation/devicetree/bindings/net/fixed-link.txt for information on |

31 | the property specifics |
32 | ||
33 | Required child nodes: | |
34 | ||
0ce5aa1d | 35 | - mdio bus node: this node should always be present regardless of the PHY |
aab5127d FF |
36 | configuration of the GENET instance |
37 | ||
38 | MDIO bus node required properties: | |
39 | ||
40 | - compatible: should contain one of "brcm,genet-mdio-v1", "brcm,genet-mdio-v2" | |
0ce5aa1d DB |
41 | "brcm,genet-mdio-v3", "brcm,genet-mdio-v4", "brcm,genet-mdio-v5", the version |
42 | has to match the parent node compatible property (e.g: brcm,genet-v4 pairs | |
43 | with brcm,genet-mdio-v4) | |
aab5127d | 44 | - reg: address and length relative to the parent node base register address |
9e5f040d FF |
45 | - #address-cells: address cell for MDIO bus addressing, should be 1 |
46 | - #size-cells: size of the cells for MDIO bus addressing, should be 0 | |
