-Optionally, the :dfn:`Clock Driver Shell` provides the routine ``Clock_exit()``
-that is scheduled to be run during system shutdown via the ``atexit()``
-routine.  The hardware-specific shutdown support is specified by
-``Clock_driver_support_shutdown_hardware()`` which is used by ``Clock_exit()``.
-It should disable the clock tick source if it was enabled.  This can be used to
-prevent clock ticks after the system is shutdown.  The
-``Clock_driver_support_shutdown_hardware()`` must be provided as a macro.  In
-case this macro is undefined, then the shutdown support is disabled.  This is
-useful for example on memory constrained systems to avoid the ``atexit()``
