Description

NXP LPC SoC series MCAN CAN-FD controller

Properties

Top level properties

These property descriptions apply to “nxp,lpc-mcan” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name

Type

Details

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>;
  };

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

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.

Deprecated properties not inherited from the base binding file.

(None)

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 “nxp,lpc-mcan” compatible.

Name

Type

Details

reg

array

register space

This property is required.

See Important properties for more information.

interrupts

array

interrupts for device

This property is required.

See Important properties for more information.

clocks

phandle-array

Clock gate information

This property is required.

status

string

indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

compatible strings

This property is required.

See Important properties for more information.

reg-names

string-array

name of each register space

interrupts-extended

compound

extended interrupt specifier for device

interrupt-names

string-array

name of each interrupt

interrupt-parent

phandle

phandle to interrupt controller node

label

string

Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

clock-names

string-array

name of each clock

#address-cells

int

number of address cells in reg property

#size-cells

int

number of size cells in reg property

dmas

wakeup-source

boolean

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.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
