   1 PHY nodes

   3 Required 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
  14 Optional 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.
  37
  38 - enet-phy-lane-swap: If set, indicates the PHY will swap the TX/RX lanes to
  39   compensate for the board being designed with the lanes swapped.
  40
  41 - eee-broken-100tx:
  42 - eee-broken-1000t:
  43 - eee-broken-10gt:
  44 - eee-broken-1000kx:
  45 - eee-broken-10gkx4:
  46 - eee-broken-10gkr:
  47   Mark the corresponding energy efficient ethernet mode as broken and
  48   request the ethernet to stop advertising it.
  49
  50 Example:
  51
  52 ethernet-phy@0 {
  53         compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22";
  54         interrupt-parent = <40000>;
  55         interrupts = <35 1>;
  56         reg = <0>;
  57 };
