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.
