PHY nodes

|
|

|
|
Required properties:
|
||
|
|
|
||
|
|
- 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
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
|
||
|
|
- compatible: Compatible list, may contain
|
||
|
|
"ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
|
||
|
|
PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
|
||
|
|
specifications. If neither of these are specified, the default is to
|
||
|
|
assume clause 22.
|
||
|
|
|
||
|
|
If the phy's identifier is known then the list may contain an entry
|
||
|
|
of the form: "ethernet-phy-idAAAA.BBBB" where
|
||
|
|
AAAA - The value of the 16 bit Phy Identifier 1 register as
|
||
|
|
4 hex digits. This is the chip vendor OUI bits 3:18
|
||
|
|
BBBB - The value of the 16 bit Phy Identifier 2 register as
|
||
|
|
4 hex digits. This is the chip vendor OUI bits 19:24,
|
||
|
|
followed by 10 bits of a vendor specific ID.
|
||
|
|
|
||
|
|
The compatible list should not contain other values than those
|
||
|
|
listed here.
|
||
|
|
|
||
|
|
- max-speed: Maximum PHY supported speed (10, 100, 1000...)
|
||
|
|
|
||
|
|
- broken-turn-around: If set, indicates the PHY device does not correctly
|
||
|
|
release the turn around line low at the end of a MDIO transaction.
|
||
|
|
|
||
|
|
- eee-broken-100tx:
|
||
|
|
- eee-broken-1000t:
|
||
|
|
- eee-broken-10gt:
|
||
|
|
- eee-broken-1000kx:
|
||
|
|
- eee-broken-10gkx4:
|
||
|
|
- eee-broken-10gkr:
|
||
|
|
Mark the corresponding energy efficient ethernet mode as broken and
|
||
|
|
request the ethernet to stop advertising it.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
ethernet-phy@0 {
|
||
|
|
compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22";
|
||
|
|
interrupt-parent = <40000>;
|
||
|
|
interrupts = <35 1>;
|
||
|
|
reg = <0>;
|
||
|
|
};
