| 3 | Required properties: |
| 4 | - compatible : Should be "fsl,<soc>-fec" |
| 5 | - reg : Address and length of the register set for the device |
| 6 | - interrupts : Should contain fec interrupt |

| 9 | Optional properties: |
| Shawn Guo | c9040af | 2012-06-27 03:45:23 +0000 | [diff] [blame] | 10 | - phy-reset-gpios : Should specify the gpio for phy reset |
| Shawn Guo | a3caad0 | 2012-06-27 03:45:24 +0000 | [diff] [blame] | 11 | - phy-reset-duration : Reset duration in milliseconds. Should present |
| 12 | only if property "phy-reset-gpios" is available. Missing the property |
| 13 | will have the duration be 1 millisecond. Numbers greater than 1000 are |
| 14 | invalid and 1 millisecond will be used instead. |
