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. - 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.
