 1PHY nodes
 2
 3Required properties:
 4
 5 - device_type : Should be "ethernet-phy"
 6 - interrupts : <a b> where a is the interrupt number and b is a
 7   field that represents an encoding of the sense and level
 8   information for the interrupt.  This should be encoded based on
 9   the information in section 2) depending on the type of interrupt
10   controller you have.
11 - interrupt-parent : the phandle for the interrupt controller that
12   services interrupts for this device.
13 - reg : The ID number for the phy, usually a small integer
14 - linux,phandle :  phandle for this node; likely referenced by an
15   ethernet controller node.

19ethernet-phy@0 {
20	linux,phandle = <2452000>
21	interrupt-parent = <40000>;
22	interrupts = <35 1>;
23	reg = <0>;
24	device_type = "ethernet-phy";
