Subject[PATCH v3 0/9] qcom: support wakeup capable GPIOs
Date
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.

Thanks,
Lina
