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.



Sensors may also have applicable pin control settings, those use the

standard bindings from pinctrl/pinctrl-bindings.txt.
