bosch,bmp388 (on spi bus)

Vendor: Bosch Sensortec GmbH

Description

Bosch BMP388 pressure sensor accessed through SPI bus

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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.
