* Texas Instruments - dp83867 Giga bit ethernet phy

Required properties:
	- reg - The ID number for the phy, usually a small integer
	- ti,rx-internal-delay - RGMII Recieve Clock Delay - see dt-bindings/net/ti-dp83867.h
		for applicable values
	- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
		for applicable values
	- ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
		for applicable values

Default child nodes are standard Ethernet PHY device
nodes as described in doc/devicetree/bindings/net/ethernet.txt

Example:

	ethernet-phy@0 {
		reg = <0>;
		ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
		ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
		ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
	};
