1 * Broadcom UniMAC MDIO bus controller
4 - compatible: should one from "brcm,genet-mdio-v1", "brcm,genet-mdio-v2",
5 "brcm,genet-mdio-v3", "brcm,genet-mdio-v4" or "brcm,unimac-mdio"
6 - reg: address and length of the regsiter set for the device, first one is the
7 base register, and the second one is optional and for indirect accesses to
8 larger than 16-bits MDIO transactions
9 - reg-names: name(s) of the register must be "mdio" and optional "mdio_indir_rw"
10 - #size-cells: must be 1
11 - #address-cells: must be 0
14 - interrupts: must be one if the interrupt is shared with the Ethernet MAC or
15 Ethernet switch this MDIO block is integrated from, or must be two, if there
16 are two separate interrupts, first one must be "mdio done" and second must be
18 - interrupt-names: must be "mdio_done_error" when there is a share interrupt fed
19 to this hardware block, or must be "mdio_done" for the first interrupt and
20 "mdio_error" for the second when there are separate interrupts
22 Child nodes of this MDIO bus controller node are standard Ethernet PHY device
23 nodes as described in Documentation/devicetree/bindings/net/phy.txt
