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. |
Deprecated properties not inherited from the base binding file.

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 the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.

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.
|
|
|
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. |
|
|
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.
|
|
|
Positive ADC input. Used only for drivers that select
the ADC_CONFIGURABLE_INPUTS Kconfig option.
|
|
|
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.
|
|
|
ADC resolution to be used for the channel.
|
|
|
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).
|
|
|
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.
|
|
|
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.
