+* 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>;
+ };
