decawave,dw1000 (on spi bus)

Vendor: Qorvo, Inc (formerly Decawave)

Description

Decawave DW1000 802.15.4 UWB transceiver

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

Interrupt pin.
The interrupt pin IRQ of DW1000 is active high output. If connected directly the MCU pin should be configured as active high.

This property is required.

reset-gpios

phandle-array

RESET pin.
The RESET pin of DW1000 is active low. If connected directly the MCU pin should be configured as active low.

This property is required.

tx-ant-delay

int

Transmitter antenna delay.

rx-ant-delay

int

Receiver antenna delay.

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.
