type: int

|
Deprecated. This property has been renamed to bitrate.
|
|
|
|
Initial bitrate in bit/s. If this is unset, the initial bitrate is set to
|
|
CONFIG_CAN_DEFAULT_BITRATE.
|
|
bitrate:
|
|
type: int
|
|
description: |
|
|
Initial bitrate in bit/s. If this is unset, the initial bitrate is set to
|
|
CONFIG_CAN_DEFAULT_BITRATE.
|
|
sample-point:
|
|
type: int
|
|
description: |
|
|
Initial sample point in per mille (e.g. 875 equals 87.5%).
|
|
|
|
If this is unset (or if it is set to 0), the initial sample point will default to 75.0% for
|
|
bitrates over 800 kbit/s, 80.0% for bitrates over 500 kbit/s, and 87.5% for all other
|
|
bitrates.

child-binding:
|

|
|
|
|
can-transceiver {
|
|
max-bitrate = <1000000>;
