| Richard Cochran | 78ca0b2 | 2012-10-29 08:45:18 +0000 | [diff] [blame] | 18 | - cpts_active_slave : Specifies the slave to use for time stamping |
| Richard Cochran | 00ab94e | 2012-10-29 08:45:19 +0000 | [diff] [blame] | 19 | - cpts_clock_mult : Numerator to convert input clock ticks into nanoseconds |
| 20 | - cpts_clock_shift : Denominator to convert input clock ticks into nanoseconds |

| 22 | - mac-address : Specifies slave MAC address |
| 23 | |
| 24 | Optional properties: |
| 25 | - ti,hwmods : Must be "cpgmac0" |
| 26 | - no_bd_ram : Must be 0 or 1 |
| Mugunthan V N | d9ba8f9 | 2013-02-11 09:52:20 +0000 | [diff] [blame] | 27 | - dual_emac : Specifies Switch to act as Dual EMAC |

| 30 | Note: "ti,hwmods" field is used to fetch the base address and irq |
| 31 | resources from TI, omap hwmod data base during device registration. |
| 32 | Future plan is to migrate hwmod data base contents into device tree |
| 33 | blob so that, all the required data will be used from device tree dts |
| 34 | file. |
