1PHY nodes

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.
21
22  If the phy's identifier is known then the list may contain an entry
23  of the form: "ethernet-phy-idAAAA.BBBB" where
24     AAAA - The value of the 16 bit Phy Identifier 1 register as
25            4 hex digits. This is the chip vendor OUI bits 3:18
26     BBBB - The value of the 16 bit Phy Identifier 2 register as
27            4 hex digits. This is the chip vendor OUI bits 19:24,
28            followed by 10 bits of a vendor specific ID.
29
30  The compatible list should not contain other values than those
31  listed here.
32
33- max-speed: Maximum PHY supported speed (10, 100, 1000...)
34
35- broken-turn-around: If set, indicates the PHY device does not correctly
36  release the turn around line low at the end of a MDIO transaction.
