*Wait for availability*

Type: ``bool``

Help
====

.. code-block:: none

    System clock source initialization waits until clock is available. In some
    systems, clock initially runs from less accurate source which has faster
    startup time and then seamlessly switches to the target clock source when
    it is ready. When this option is picked, system clock is available after
    system clock driver initialization but it may be less accurate. Option is
    equivalent to waiting for stability if clock source does not have
    intermediate state.
