Common MDIO bus properties.
|
||
|
|
|
||
|
|
These are generic properties that can apply to any MDIO bus.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- device-name - If present it is used to name the device and MDIO bus.
|
||
|
|
The name must be unique and must not contain spaces.
|
||
|
|
|
||
|
|
A list of child nodes, one per device on the bus is expected. These could be
|
||
|
|
PHYs, switches or similar devices and child nodes should follow the specific
|
||
|
|
binding for the device type.
|
||
|
|
|
||
|
|
Example :
|
||
|
|
This example shows the structure used for the external MDIO bus on NXP LS1028A
|
||
|
|
RDB board. Note that this MDIO device is an integrated PCI function and
|
||
|
|
requires no compatible property for probing.
