+PHY nodes
+
+Required properties:
+
+ - device_type : Should be "ethernet-phy"
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+ - reg : The ID number for the phy, usually a small integer
+ - linux,phandle : phandle for this node; likely referenced by an
+ ethernet controller node.
+
+Example:
+
+ethernet-phy@0 {
+ linux,phandle = <2452000>
+ interrupt-parent = <40000>;
+ interrupts = <35 1>;
+ reg = <0>;
+ device_type = "ethernet-phy";
+};
