+* Texas Instruments - dp83867 Giga bit ethernet phy
+
+Required properties:
+ - 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:
+
+&mac {
+ pinctrl-0 = <&davinci_mdio_default>;
+ pinctrl-1 = <&davinci_mdio_sleep>;
+ status = "okay";
+
+ ti,rx_int_delay = <DP83867_RGMIIDCTL_1_50_NS>;
+ ti,tx_int_delay = <DP83867_RGMIIDCTL_2_50_NS>;
+ ti,fifo_depth = <DP83867_PHYCR_FIFO_DEPTH_8_B_NIB>;
