| 18 | description: |
| 19 | Transmit amplitude voltages in microvolts, peak-to-peak. If this property |
| 20 | contains multiple values for various PHY modes, the |
| 21 | 'tx-p2p-microvolt-names' property must be provided and contain |
| 22 | corresponding mode names. |
| 23 | |
| 24 | tx-p2p-microvolt-names: |
| 25 | description: | |
| 26 | Names of the modes corresponding to voltages in the 'tx-p2p-microvolt' |
| 27 | property. Required only if multiple voltages are provided. |
| 28 | |
| 29 | If a value of 'default' is provided, the system should use it for any PHY |
| 30 | mode that is otherwise not defined here. If 'default' is not provided, the |
| 31 | system should use manufacturer default value. |
