 - ``/ibm,opal/`` compatible property now just lists ``ibm,opal-v3`` and no longer ``ibm,opal-v2`` (power9 and above only)
 - Rename ``fsp-ipl-side`` as ``sp-ipl-side`` in ``/ipl-params``
+- Add interrupt-parent property for ``/ibm,opal/ipmi`` node on POWER9 and above
+  to make use of OPAL irqchip rather than event interface in linux.
