IBI Data Fifo Threashold Value
Default value: |
|
|
Frequency of the SCL signal used for I3C transfers. When undefined,
use the controller default or as specified by the I3C specification.
|
|
|
Frequency of the SCL signal used for I2C transfers. When undefined
and there are I2C devices attached to the bus, look at the Legacy
Virtual Register (LVR) of all connected I2C devices to determine
the maximum allowed frequency.

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 “cdns,i3c” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
