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.
