st,stm32-can

Vendor: STMicroelectronics

Description

These nodes are “can” bus nodes.

STM32 CAN controller

Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name

pinctrl-0

phandles

 
GPIO pin configuration for CAN RX and TX. The phandles are
expected to reference pinctrl nodes, e.g.

  pinctrl-0 = <&can1_rx_pa11 &can1_tx_pa12>;

master-can-reg

int

 
master can reg when different from current instance

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)

This property is required.

phase-seg1

int

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

This property is required.

phase-seg2

int

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

This property is required.

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 “st,stm32-can” compatible.
