ti,ads1013 (on i2c bus)

Vendor: Texas Instruments

Description

Texas Instrument ADS1013 I2C ADC

Properties

Top level properties

These property descriptions apply to “ti,ads1013” nodes themselves. This page also describes child node properties in the following sections.

Node specific properties

Deprecated node specific properties

Base properties

Properties not inherited from the base binding file.

Name

Type

Details

#io-channel-cells

int

This property is required.

Constant value: 1

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.

Deprecated properties not inherited from the base binding file.

(None)

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “ti,ads1013” compatible.

Name

Type

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

This property is required.

See Important properties for more information.

#address-cells

indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

This property is required.

See Important properties for more information.

string-array

 
Provided names of DMA channel specifiers

string-array

 
Provided names of IO channel specifiers

mboxes

phandle-array

 
mailbox / IPM channels specifiers

mbox-names

string-array

 
Provided names of mailbox / IPM channel specifiers

wakeup-source

boolean

 
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.

power-domain

phandle

 
Power domain the device belongs to.

The device will be notified when the power domain it belongs to is either
suspended or resumed.

reg

array

- ADC_GAIN_24:  x 24
- ADC_GAIN_32:  x 32
- ADC_GAIN_64:  x 64
- ADC_GAIN_128: x 128

This property is required.

Legal values: 'ADC_GAIN_1_6', 'ADC_GAIN_1_5', 'ADC_GAIN_1_4', 'ADC_GAIN_1_3', 'ADC_GAIN_2_5', 'ADC_GAIN_1_2', 'ADC_GAIN_2_3', 'ADC_GAIN_4_5', 'ADC_GAIN_1', 'ADC_GAIN_2', 'ADC_GAIN_3', 'ADC_GAIN_4', 'ADC_GAIN_6', 'ADC_GAIN_8', 'ADC_GAIN_12', 'ADC_GAIN_16', 'ADC_GAIN_24', 'ADC_GAIN_32', 'ADC_GAIN_64', 'ADC_GAIN_128'

zephyr,reference

string

 
Reference selection:
- ADC_REF_VDD_1:     VDD
- ADC_REF_VDD_1_2:   VDD/2
- ADC_REF_VDD_1_3:   VDD/3
- ADC_REF_VDD_1_4:   VDD/4
- ADC_REF_INTERNAL:  Internal
- ADC_REF_EXTERNAL0: External, input 0
- ADC_REF_EXTERNAL1: External, input 1

This property is required.

Legal values: 'ADC_REF_VDD_1', 'ADC_REF_VDD_1_2', 'ADC_REF_VDD_1_3', 'ADC_REF_VDD_1_4', 'ADC_REF_INTERNAL', 'ADC_REF_EXTERNAL0', 'ADC_REF_EXTERNAL1'

zephyr,vref-mv

int

 
This property can be used to specify the voltage (in millivolts)
of the reference selected for this channel, so that applications
can get that value if needed for some calculations.
For the internal reference, the voltage can be usually obtained with
a dedicated ADC API call, so there is no need to use this property
in that case, but for other references this property can be useful.

zephyr,acquisition-time

int

 
Acquisition time.
Use the ADC_ACQ_TIME macro to compose the value for this property
or pass ADC_ACQ_TIME_DEFAULT to use the default setting for a given
hardware (e.g. when the hardware does not allow to configure the
acquisition time).

This property is required.

zephyr,input-positive

int

 
Positive ADC input. Used only for drivers that select
the ADC_CONFIGURABLE_INPUTS Kconfig option.

zephyr,input-negative

int

 
Negative ADC input. Used only for drivers that select
the ADC_CONFIGURABLE_INPUTS Kconfig option.
When specified, the channel is to be used in differential input mode,
otherwise, single-ended mode is used.

zephyr,resolution

int

 
ADC resolution to be used for the channel.

zephyr,oversampling

int

 
Oversampling setting to be used for the channel.
When specified, each sample is averaged from 2^N conversion results
(where N is the provided value).
