STMicroelectronics LIS3DH 3-axis accelerometer

Properties

Properties not inherited from the base binding file.

Details

supply-gpios

phandle-array

 
GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

 
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

friendly-name

string

 
Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).

irq-gpios

phandle-array

 
The INT1 and (optional) INT2 signal connections.  These signals
are active-high as produced by the sensor.

int1-gpio-config

int

 
Select the interrupt configuration for INT1 gpio.

The default of 0 is the most common situation to avoid multiple interrupts
to be triggered by same event.

- 0 # LIS2DH_DT_GPIO_INT_EDGE_BOTH
- 1 # LIS2DH_DT_GPIO_INT_EDGE_RISING
- 2 # LIS2DH_DT_GPIO_INT_EDGE_FALLING
- 3 # LIS2DH_DT_GPIO_INT_LEVEL_HIGH
- 4 # LIS2DH_DT_GPIO_INT_LEVEL_LOW

Legal values: 0, 1, 2, 3, 4

int2-gpio-config

int

 
Select the interrupt configuration for INT2 gpio.

The default of 0 is the most common situation to avoid multiple interrupts
to be triggered by same event.

- 0 # LIS2DH_DT_GPIO_INT_EDGE_BOTH
- 1 # LIS2DH_DT_GPIO_INT_EDGE_RISING
- 2 # LIS2DH_DT_GPIO_INT_EDGE_FALLING
- 3 # LIS2DH_DT_GPIO_INT_LEVEL_HIGH
- 4 # LIS2DH_DT_GPIO_INT_LEVEL_LOW

Legal values: 0, 1, 2, 3, 4

disconnect-sdo-sa0-pull-up

boolean

 
Indicates the device driver should disconnect SDO/SA0 pull-up
during device initialization (e.g. to save current
leakage). Note that only subset of devices supported by this
binding have SDO/SA0 pull-up (e.g. LIS2DH12, LIS3DH).

anym-on-int1

boolean

 
Indicates that the device driver should use interrupt 1
for any movement. This is for boards that only have one
interrupt line connected from the sensor to the processor.

anym-no-latch

boolean

 
Disable the latching of interrupts for any movement.

anym-mode

int

 
Select the interrupt mode for any movement.

The default of 0 is the power-on-reset value.

- 0 # LIS2DH_DT_ANYM_OR_COMBINATION
- 1 # LIS2DH_DT_ANYM_6D_MOVEMENT
- 2 # LIS2DH_DT_ANYM_AND_COMBINATION
- 3 # LIS2DH_DT_ANYM_6D_POSITION

Legal values: 0, 1, 2, 3
