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. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
