| 2 | |
| 3 | These are generic properties that can apply to any MDIO bus. |
| 4 | |
| 5 | Optional properties: |
| 6 | - device-name - If present it is used to name the device and MDIO bus. |
| 7 | The name must be unique and must not contain spaces. |
| 8 | |
| 9 | A list of child nodes, one per device on the bus is expected. These could be |
| 10 | PHYs, switches or similar devices and child nodes should follow the specific |
| 11 | binding for the device type. |
| 12 | |
| 13 | Example : |
| 14 | This example shows the structure used for the external MDIO bus on NXP LS1028A |
| 15 | RDB board. Note that this MDIO device is an integrated PCI function and |
| 16 | requires no compatible property for probing. |
