Hi Magnus, Hi all,

I do not expect this code to go through the renesas tree.  However, in
order to provide a basis for work on renesas SoCs I have added this patch
to the topic/intc-external-irq topic branch in the reneas tree on
kernel.org and merged it into topic/all+next.

In other words, I am not picking this series up to merge it or add it to
linux-next, rather I am storing it for reference.
