3Required properties:
4
5 - interrupts : <a b> where a is the interrupt number and b is a
6   field that represents an encoding of the sense and level
7   information for the interrupt.  This should be encoded based on
8   the information in section 2) depending on the type of interrupt
9   controller you have.
10 - interrupt-parent : the phandle for the interrupt controller that
11   services interrupts for this device.
12 - reg : The ID number for the phy, usually a small integer
13
14Optional Properties:
15
16- compatible: Compatible list, may contain
17  "ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
18  PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
19  specifications. If neither of these are specified, the default is to
20  assume clause 22. The compatible list may also contain other
21  elements.
22
23  If the phy's identifier is known then the list may contain an entry
24  of the form: "ethernet-phy-idAAAA.BBBB" where
25     AAAA - The value of the 16 bit Phy Identifier 1 register as
26            4 hex digits. This is the chip vendor OUI bits 3:18
27     BBBB - The value of the 16 bit Phy Identifier 2 register as
28            4 hex digits. This is the chip vendor OUI bits 19:24,
29            followed by 10 bits of a vendor specific ID.
30
31- max-speed: Maximum PHY supported speed (10, 100, 1000...)

33Example:

35ethernet-phy@0 {
36	compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22";
37	interrupt-parent = <40000>;
38	interrupts = <35 1>;
39	reg = <0>;
