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.
