zephyr,native-linux-can

Vendor: Zephyr-specific binding

Note

An implementation of a driver matching this compatible is available in drivers/can/can_native_linux.c.

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

bitrate

int

Initial bitrate in bit/s. If this is unset, the initial bitrate is set to
CONFIG_CAN_DEFAULT_BITRATE.

sample-point

int

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

phandle

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>;
  };

bitrate-data

int

Initial data phase bitrate in bit/s.  If this is unset, the initial data phase bitrate is set
to CONFIG_CAN_DEFAULT_BITRATE_DATA.

sample-point-data

int

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.

host-interface

string

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.

Child node properties

Name

Type

Details

min-bitrate

int

The minimum bitrate supported by the CAN transceiver in bits/s.

max-bitrate

int

The maximum bitrate supported by the CAN transceiver in bits/s.

This property is required.
