adi,adxl372 (on spi bus)

Vendor: Analog Devices, Inc.

Description

ADXL372 3-axis high-g accelerometer, accessed through SPI bus

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int1-gpios

phandle-array

 
The INT1 signal defaults to active high as produced by the
sensor.  The property value should ensure the flags properly
describe the signal that is presented to the driver.

spi-max-frequency

int

 
Maximum clock frequency of device's SPI interface in Hz

This property is required.

duplex

int

 
Duplex mode, full or half. By default it's always full duplex thus 0
as this is, by far, the most common mode.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0    SPI_FULL_DUPLEX
  2048 SPI_HALF_DUPLEX

Legal values: 0, 2048

frame-format

int

 
Motorola or TI frame format. By default it's always Motorola's,
thus 0 as this is, by far, the most common format.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0     SPI_FRAME_FORMAT_MOTOROLA
  32768 SPI_FRAME_FORMAT_TI

Legal values: 0, 32768

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.

odr

int

 
Accelerometer sampling frequency (ODR). Default is power on reset value.
  0 # 400Hz
  1 # 800Hz
  2 # 1600Hz
  3 # 3200Hz
  4 # 6400Hz

Legal values: 0, 1, 2, 3, 4

bw

int

 
Low-Pass (Antialiasing) Filter corner frequency. Default is power on reset value.
  0 # 200Hz
  1 # 400Hz
  2 # 800Hz
  3 # 1600Hz
  4 # 3200Hz
  12 # Disabled

Default value: 12

Legal values: 0, 1, 2, 3, 4, 12

hpf

int

 
High-Pass Filter corner frequency. Default is power on reset value.
  0 # ODR/210
  1 # ODR/411
  2 # ODR/812
  3 # ODR/1616
  4 # Disabled

Default value: 4

Legal values: 0, 1, 2, 3, 4

friendly-name

string

 
Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
