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. |
