Properties

Node specific propertiesDeprecated node specific propertiesBase properties

Properties not inherited from the base binding file.

Name	Type	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.
spi-max-frequency	int	Maximum clock frequency of device's SPI interface in Hz This property is required.
duplex	int	Duplex mode, full or half. By default it's always full duplex thus 0 as this is, by far, the most common mode. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FULL_DUPLEX 2048 SPI_HALF_DUPLEX Legal values: 0, 2048
frame-format	int	Motorola or TI frame format. By default it's always Motorola's, thus 0 as this is, by far, the most common format. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FRAME_FORMAT_MOTOROLA 32768 SPI_FRAME_FORMAT_TI Legal values: 0, 32768
spi-cpol	boolean	SPI clock polarity which indicates the clock idle state. If it is used, the clock idle state is logic high; otherwise, low.
spi-cpha	boolean	SPI clock phase that indicates on which edge data is sampled. If it is used, data is sampled on the second edge; otherwise, on the first edge.
spi-hold-cs	boolean	In some cases, it is necessary for the master to manage SPI chip select under software control, so that multiple spi transactions can be performed without releasing it. A typical use case is variable length SPI packets where the first spi transaction reads the length and the second spi transaction reads length bytes.
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	DRDY pin This pin defaults to active high when produced by the sensor. The property value should ensure the flags properly describe the signal that is presented to the driver.
range	int	Range in g. Default is power-up configuration. - 16 # 16g (0.488 mg/LSB) - 8 # 8g (0.244 mg/LSB) - 4 # 4g (0.122 mg/LSB) - 2 # 2g (0.061 mg/LSB) Default value: 2 Legal values: 16, 8, 4, 2
power-mode	int	Specify the sensor power mode. Default is power-down mode - 0 # LIS2DS12_DT_POWER_DOWN - 1 # LIS2DS12_DT_LOW_POWER - 2 # LIS2DS12_DT_HIGH_RESOLUTION - 3 # LIS2DS12_DT_HIGH_FREQUENCY Legal values: 0, 1, 2, 3
odr	int	Specify the default output data rate expressed in samples per second (Hz). Default is power-down mode - 0 # LIS2DS12_DT_ODR_OFF - 1 # LIS2DS12_DT_ODR_1Hz_LP - 2 # LIS2DS12_DT_ODR_12Hz5 - 3 # LIS2DS12_DT_ODR_25Hz - 4 # LIS2DS12_DT_ODR_50Hz - 5 # LIS2DS12_DT_ODR_100Hz - 6 # LIS2DS12_DT_ODR_200Hz - 7 # LIS2DS12_DT_ODR_400Hz - 8 # LIS2DS12_DT_ODR_800Hz - 9 # LIS2DS12_DT_ODR_1600Hz - 10 # LIS2DS12_DT_ODR_3200Hz_HF - 11 # LIS2DS12_DT_ODR_6400Hz_HF Legal values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
