| properties: |
| tx-p2p-microvolt: |
| description: |
| Transmit amplitude voltages in microvolts, peak-to-peak. If this property |
| contains multiple values for various PHY modes, the |
| 'tx-p2p-microvolt-names' property must be provided and contain |
| corresponding mode names. |
| |
| tx-p2p-microvolt-names: |
| description: | |
| Names of the modes corresponding to voltages in the 'tx-p2p-microvolt' |
| property. Required only if multiple voltages are provided. |
| |
| If a value of 'default' is provided, the system should use it for any PHY |
| mode that is otherwise not defined here. If 'default' is not provided, the |
| system should use manufacturer default value. |
