1	PHY nodes
2	
3	Required 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.
16	
17	Optional Properties:
18	
19	- compatible: Compatible list, may contain
20	  "ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
21	  PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
22	  specifications. If neither of these are specified, the default is to
23	  assume clause 22. The compatible list may also contain other
24	  elements.
25	
26	Example:
27	
28	ethernet-phy@0 {
29		compatible = "ethernet-phy-ieee802.3-c22";
30		linux,phandle = <2452000>;
31		interrupt-parent = <40000>;
32		interrupts = <35 1>;
33		reg = <0>;
34		device_type = "ethernet-phy";
35	};
