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.
