st,stm32-fdcan

Vendor: STMicroelectronics

Description

ST STM32 FDCAN CAN-FD controller

Properties

Top level properties

These property descriptions apply to “st,stm32-fdcan” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name

Type

Details

clk-divider

int

Divides the kernel clock giving the time quanta clock that is fed to the
CAN core(FDCAN_CKDIV).
Note that the divisor is common to all 'st,stm32-fdcan' instances.
Divide by 1 is the peripherals reset value and remains set unless
this property is configured.

Legal values: 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30

bus-speed-data

int

data phase bus speed in Baud/s

This property is required.

sjw-data

int

Resynchronization jump width for the data phase. (ISO11898-1:2015)

This property is required.

prop-seg-data

int

Time quantums of propagation segment for the data phase. (ISO11898-1:2015)

phase-seg1-data

int

Time quantums of phase buffer 1 segment for the data phase. (ISO11898-1:2015)

phase-seg2-data

int

Time quantums of phase buffer 2 segment for the data phase. (ISO11898-1:2015)

sample-point-data

int

Sample point in permille for the data phase. This param is required if segments are not given. If the sample point is given, the segments are ignored.

tx-delay-comp-offset

int

bus-speed

int

bus speed in Baud/s

This property is required.

sjw

int

Resynchronization jump width (ISO 11898-1)

This property is required.

prop-seg

int

Time quantums of propagation segment (ISO 11898-1)

phase-seg1

int

Time quantums of phase buffer 1 segment (ISO 11898-1)

phase-seg2

int

Time quantums of phase buffer 2 segment (ISO 11898-1)

sample-point

int

Sample point in permille. This param is required if segments are not given. If the sample point is given, the segments are ignored.

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.

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

Child node properties

Name

Type

Details

max-bitrate

int

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

This property is required.
