Properties

Top level properties

These property descriptions apply to “nxp,vf610-adc” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name

Type

Details

#io-channel-cells

int

This property is required.

Constant value: 1

clk-source

int

 
Select adc clock source: 0 clock from IPG, 1 clock from IPG divided 2, 2 async clock

This property is required.

clk-divider

int

 
Select clock divider: 0 clock divided by 1, 1 clock divided by 2, 2 clock divided by 4,
3 clock divided by 8

This property is required.

rdc

int

 
Set the RDC permission for this peripheral: the RDC controls which
processor can access to this peripheral. User can select to assign this
peripheral to the M4 processor, A9 processor or both with R/W or RW
permissions. To set wanted permission a user should use the helper
macro RDC_DOMAIN_PERM(domain,permission) where domain must be one of
M4_DOMAIN_ID or A9_DOMAIN_ID and permission one among
RDC_DOMAIN_PERM_NONE, RDC_DOMAIN_PERM_W, RDC_DOMAIN_PERM_R,
RDC_DOMAIN_PERM_RW. Example to allow both processor to read/write to
this peripheral a user should put:
rdc = <(RDC_DOMAIN_PERM(A9_DOMAIN_ID, RDC_DOMAIN_PERM_RW) |
        RDC_DOMAIN_PERM(M4_DOMAIN_ID, RDC_DOMAIN_PERM_RW))>;

This property is required.

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,differential

boolean

 
When set, selects differential input mode for the channel. Otherwise,
single-ended mode is used unless the zephyr,input-negative property is
specified, in which case the differential mode is selected implicitly.

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, implies the differential input mode for the channel.

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).

zephyr,current-source-pin

uint8-array

 
Output pin selection for the current sources. The actual
interpretation depends on the driver. This is used only for drivers
which select the ADC_CONFIGURABLE_EXCITATION_CURRENT_SOURCE_PIN
Kconfig option.

zephyr,vbias-pins

int

 
Output pin selection for the bias voltage. The actual interpretation
depends on the driver. This is used only for drivers which select
the ADC_CONFIGURABLE_VBIAS_PIN Kconfig option.
