STMicroelectronics MEMS sensors

2


3
The STMicroelectronics sensor devices are pretty straight-forward I2C or

4
SPI devices, all sharing the same device tree descriptions no matter what

5
type of sensor it is.

6


7
Required properties:

8
- compatible: see the list of valid compatible strings below

9
- reg: the I2C or SPI address the device will respond to

10


11
Optional properties:

12
- vdd-supply: an optional regulator that needs to be on to provide VDD

13
  power to the sensor.

14
- vddio-supply: an optional regulator that needs to be on to provide the

15
  VDD IO power to the sensor.

16
- st,drdy-int-pin: the pin on the package that will be used to signal

17
  "data ready" (valid values: 1 or 2). This property is not configurable

18
  on all sensors.

19
- drive-open-drain: the interrupt/data ready line will be configured

20
  as open drain, which is useful if several sensors share the same

21
  interrupt line. (This binding is taken from pinctrl/pinctrl-bindings.txt)

22
  This is a boolean property.

23


24
Sensors may also have applicable pin control settings, those use the

25
standard bindings from pinctrl/pinctrl-bindings.txt.
