# Common fields for CAN controllers
include: base.yaml
properties:
bus-speed:
type: int
deprecated: true
description: |
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.
phys:
type: phandle
description: |
Actively controlled CAN transceiver.
Example:
transceiver0: can-phy0 {
compatible = "nxp,tja1040", "can-transceiver-gpio";
standby-gpios = <gpioa 0 GPIO_ACTIVE_HIGH>;
max-bitrate = <1000000>;
#phy-cells = <0>;
};
&can0 {
status = "okay";
phys = <&transceiver0>;
};
child-binding:
description: |
Passive CAN transceiver. The child node must be named "can-transceiver".
Example:
&can0 {
status = "okay";
can-transceiver {
max-bitrate = <1000000>;
};
};
properties:
min-bitrate:
type: int
description: |
The minimum bitrate supported by the CAN transceiver in bits/s.
max-bitrate:
type: int
required: true
description: |
The maximum bitrate supported by the CAN transceiver in bits/s.
