TI ADS114S0x GPIO controller binding
Properties
Top level properties
These property descriptions apply to “ti,ads114s0x-gpio” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.

Convey's this node is a GPIO controller
This property is required. |
|
|
Number of items to expect in a GPIO specifier
This property is required. Constant value: |
|
|
Number of gpios supported
This property is required. Default value: Constant value: |
|
|
If not all the GPIOs at offsets 0...N-1 are usable for ngpios = <N>, then
this property contains an additional set of tuples which specify which GPIOs
are unusable. This property indicates the start and size of the GPIOs
that can't be used.
For example, setting "gpio-reserved-ranges = <3 2>, <10 1>;" means that
GPIO offsets 3, 4, and 10 are not usable, even if ngpios = <18>.

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,ads114s0x-gpio” compatible.

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.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device

|
Conveys this node is a GPIO hog.
This property is required. |
|
|
This is an array of GPIO specifiers (e.g. pin, flags) to be hogged. The number of array
entries must be an integer multiple of the number of GPIO specifier cells for the parent
GPIO controller.
This property is required. |
|
|
If this property is set, the GPIO is configured as an input. This property takes
precedence over the output-low and output-high properties.
|
|
|
If this property is set, the GPIO is configured as an output set to logical low. This
property takes precedence over the output-high property.
|
|
|
If this property is set, the GPIO is configured as an output set to logical high.
|
|
|
Optional GPIO line name.
