cypress,psoc6-pinctrl
Vendor: Cypress Semiconductor Corporation
Description
Cypress PSoC-6 Pinctrl container node
The Cypress PSoC-6 pins implements following pin configuration option:
* bias-pull-up
* bias-pull-down
* drive-open-drain
* drive-open-source
* drive-push-pull (strong)
* input-enable (input-buffer)
These options define devicetree flags that are converted to SoC flags at
CY_PSOC6_PIN_FLAGS().
Properties
Top level properties
These property descriptions apply to “cypress,psoc6-pinctrl” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.
(None)
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 “cypress,psoc6-pinctrl” 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.

|
|
|
enable output on a pin without actively driving it (such as enabling
an output buffer)
|
|
|
set the pin to output mode with low level
|
|
|

|
|
indicate this is sleep related state which will be programmed into
the registers for the sleep state
|
|
|
set the slew rate
|
|
|
This affects the expected clock skew on input pins and the delay
before latching a value to an output pin. Typically indicates how
many double-inverters are used to delay the signal.
