STMicroelectronics MEMS sensors
The STMicroelectronics sensor devices are pretty straight-forward I2C or
SPI devices, all sharing the same device tree descriptions no matter what
type of sensor it is.
Required properties:
- compatible: see the list of valid compatible strings below
- reg: the I2C or SPI address the device will respond to
Optional properties:
- vdd-supply: an optional regulator that needs to be on to provide VDD
power to the sensor.
- vddio-supply: an optional regulator that needs to be on to provide the
VDD IO power to the sensor.
- st,drdy-int-pin: the pin on the package that will be used to signal
"data ready" (valid values: 1 or 2). This property is not configurable
on all sensors.
iio: st_sensors: support open drain mode Some types of ST Sensors can be connected to the same IRQ line as other peripherals using open drain. Add a device tree binding and a sensor data property to flip the right bit in the interrupt control register to enable open drain mode on the INT line. If the line is set to be open drain, also tag on IRQF_SHARED to the IRQ flags when requesting the interrupt, as the whole point of using open drain interrupt lines is to share them with more than one peripheral (wire-or).

- drive-open-drain: the interrupt/data ready line will be configured
as open drain, which is useful if several sensors share the same
interrupt line. (This binding is taken from pinctrl/pinctrl-bindings.txt)
This is a boolean property.

Sensors may also have applicable pin control settings, those use the
standard bindings from pinctrl/pinctrl-bindings.txt.
