|
|
Maximum clock frequency of device's SPI interface in Hz
This property is required. |
|
|
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: |
|
|
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: |
|
|
SPI clock polarity which indicates the clock idle state.
If it is used, the clock idle state is logic high; otherwise, low.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
INT1 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.
|
|
|
INT2 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.
|
|
|
Select DRDY pin number (1 or 2).
This number represents which of the two interrupt pins
(INT1 or INT2) the drdy line is attached to. This property is not
mandatory and if not present it defaults to 1 which is the
configuration at power-up.

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
