| 2 | | - |
|---|
| 3 | | -These are generic properties that can apply to any MDIO bus. |
|---|
| 4 | | - |
|---|
| 5 | | -Optional properties: |
|---|
| 6 | | -- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO |
|---|
| 7 | | - bus. |
|---|
| 8 | | -- reset-delay-us: RESET pulse width in microseconds. |
|---|
| 9 | | - |
|---|
| 10 | | -A list of child nodes, one per device on the bus is expected. These |
|---|
| 11 | | -should follow the generic phy.txt, or a device specific binding document. |
|---|
| 12 | | - |
|---|
| 13 | | -The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and |
|---|
| 14 | | -applies to all PHY devices. It must therefore be appropriately determined based |
|---|
| 15 | | -on all PHY requirements (maximum value of all per-PHY RESET pulse widths). |

|---|
| 19 | | -required for the TI Davinci MDIO driver. |
