SMSC LAN87xx Ethernet PHY
|
|
|
|
Some boards require special tuning values. Configure them
|
|
through an Ethernet OF device node.
|
|
|
|
Optional properties:
|
|
|
|
- clocks:
|
|
The clock used as phy reference clock and is connected to phy
|
|
pin XTAL1/CLKIN.
|
|
|
|
- smsc,disable-energy-detect:
|
|
If set, do not enable energy detect mode for the SMSC phy.
|
|
default: enable energy detect mode
|
|
|
|
Examples:
|
|
smsc phy with disabled energy detect mode on an am335x based board.

|
|
pinctrl-1 = <&davinci_mdio_sleep>;
