Deprecated node specific properties

Base properties

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)

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.

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.

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 “st,stm32h7-fdcan” compatible.

Name

Type

Details

clocks

phandle-array

 
Clock gate information

This property is required.

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.

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

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.
