|  | 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"; | 
|  | }; |
