bosch,bmp388 (on i2c bus)

Vendor: Bosch Sensortec GmbH

Description

Bosch BMP388 pressure sensor accessed through I2C bus

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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.

int-gpios

phandle-array

osr-press

int

Default pressure oversampling rate. Only the following values are
allowed:
  1 sample, 16-bit, 2.64 Pa
  2 samples, 17-bit, 1.32 Pa
  4 samples, 18-bit, 0.66 Pa (default; chip reset value)
  8 samples, 19-bit, 0.33 Pa
  16 samples, 20-bit, 0.17 Pa
  32 Samples, 21-bit, 0.085 Pa

Default value: 4

Legal values: 1, 2, 4, 8, 16, 32

osr-temp

int

Default temperature oversampling rate. Only the following values are
allowed:
  1 sample, 16-bit, .0050 C (default; chip reset value)
  2 samples, 17-bit, .0025 C
  4 samples, 18-bit, .0012 C
  8 samples, 19-bit, .0006 C
  16 samples, 20-bit, .0003 C
  32 Samples, 21-bit, .00015 C

Default value: 1

Legal values: 1, 2, 4, 8, 16, 32

iir-filter

int

Default IIR filter coefficient. The default 0 is the chip reset value.

Legal values: 0, 1, 3, 7, 15, 31, 63, 127

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).
