+Clock callbacks
+---------------
+
+You can give a clock a callback function in several ways:
+
+ * by passing it as an argument to ``qdev_init_clock_in()``
+ * as an argument to the ``QDEV_CLOCK_IN()`` macro initializing an
+ array to be passed to ``qdev_init_clocks()``
+ * by directly calling the ``clock_set_callback()`` function
+
+The callback function must be of this type:
+
+.. code-block:: c
+
+ typedef void ClockCallback(void *opaque, ClockEvent event);
+
+The ``opaque`` argument is the pointer passed to ``qdev_init_clock_in()``
+or ``clock_set_callback()``; for ``qdev_init_clocks()`` it is the
+``dev`` device pointer.
+
+The ``event`` argument specifies why the callback has been called.
+When you register the callback you specify a mask of ClockEvent values
+that you are interested in. The callback will only be called for those
+events.
+
+The events currently supported are:
+
+ * ``ClockUpdate`` : called after the input clock's period has changed
+
+Note that a clock only has one callback: it is not possible to register
+different functions for different events. You must register a single
+callback which listens for all of the events you are interested in,
+and use the ``event`` argument to identify which event has happened.
