Vendor: Zephyr-specific binding
Description
Zephyr CAN driver using Linux SocketCAN
Properties
Top level properties
These property descriptions apply to “zephyr,native-linux-can” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.
Name |
Type |
Details |
|---|---|---|
|
|
Initial bitrate in bit/s. If this is unset, the initial bitrate is set to
CONFIG_CAN_DEFAULT_BITRATE.
|
|
|
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.
|
|
|
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>;
};
|
|
|
Initial data phase bitrate in bit/s. If this is unset, the initial data phase bitrate is set
to CONFIG_CAN_DEFAULT_BITRATE_DATA.
|
|
|
Initial data phase 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.
|
|
|
Linux host interface name (e.g. zcan0, vcan0, can0, ...).
This property can be overridden using the --can-if command-line
option. Note that it applies for every instance of this driver.
This property is required. |
Deprecated properties not inherited from the base binding file.

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.
|
|
|
Deprecated. This property has been renamed to bitrate-data.
Initial data phase bitrate in bit/s. If this is unset, the initial data phase bitrate is set
to CONFIG_CAN_DEFAULT_BITRATE_DATA.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “zephyr,native-linux-can” compatible.

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device

|
|
|
name of each interrupt
|
|
|
phandle to interrupt controller node
|
|
|
Human readable string describing the device (used as device_get_binding() argument)
See Important properties for more information. This property is deprecated. |
