Type

Details

clk-source

int

CAN engine clock source

This property is required.

bus-speed

int

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>;
  };

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
