Hi all, This series is based on idea of setting up a wakeup parent interrupt controller for GPIOs that are wakeup capable. The patch is based on Thierry's hierarchical GPIO irqdomains. Much of the idea stem's from Stephen's suggestions in [1] with some fixes. I am posting this series to help with the discussions around this approach. Please take a look at the series and let me know your comments. We need to find a good place to add the document the generic irqdomain-map bindings.
