| * Marvell MDIO Ethernet Controller interface |
| |
| The Ethernet controllers of the Marvel Kirkwood, Dove, Orion5x, |
| MV78xx0, Armada 370 and Armada XP have an identical unit that provides |
| an interface with the MDIO bus. This driver handles this MDIO |
| interface. |
| |
| Required properties: |
| - compatible: "marvell,orion-mdio" |
| - reg: address and length of the SMI register |
| |
| Optional properties: |
| - interrupts: interrupt line number for the SMI error/done interrupt |
| - clocks: Phandle to the clock control device and gate bit |
| |
| The child nodes of the MDIO driver are the individual PHY devices |
| connected to this MDIO bus. They must have a "reg" property given the |
| PHY address on the MDIO bus. |
| |
| Example at the SoC level: |
| |
| mdio { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| compatible = "marvell,orion-mdio"; |
| reg = <0xd0072004 0x4>; |
| }; |
| |
| And at the board level: |
| |
| mdio { |
| phy0: ethernet-phy@0 { |
| reg = <0>; |
| }; |
| |
| phy1: ethernet-phy@1 { |
| reg = <1>; |
| }; |
| } |
