1 * Broadcom UniMAC MDIO bus controller 2 3 Required properties: 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 12 13 Optional properties: 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 17 for "mdio error" 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 21 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 24 25 Example: 26 27 mdio@403c0 { 28 compatible = "brcm,unimac-mdio"; 29 reg = <0x403c0 0x8 0x40300 0x18>; 30 reg-names = "mdio", "mdio_indir_rw"; 31 #size-cells = <1>; 32 #address-cells = <0>; 33 34 ... 35 phy@0 { 36 compatible = "ethernet-phy-ieee802.3-c22"; 37 reg = <0>; 38 }; 39 };
