microchip,mcp2515 (on spi bus)

Vendor: Microchip Technology Inc.

Description

These nodes are “can” bus nodes.

MCP2515 SPI CAN controller

Properties

Properties not inherited from the base binding file.

Name

Type

Details

osc-freq

int

 
Frequency of the external oscillator

This property is required.

int-gpios

phandle-array

 
> Interrupt pin.
This pin signals active low when produced by the controller. The property value should ensure the flags properly describe the signal that is presented to the driver.

This property is required.

spi-max-frequency

int

 
Maximum clock frequency of device's SPI interface in Hz

This property is required.

supply-gpios

phandle-array

 
GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

 
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

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.
