From: Rob Herring <rob.herring@calxeda.com>
This series adds irq domain support for generic irq chip and updates pl061 gpio and imx tzic to use it.
Once again, this is has been significantly re-worked from the previous version. It's simply not possible to add domain support in a transparent way. So now a wrapper function is added to setup a domain and alloc and setup N gen irq chips.
There was some discussion about supporting multiple banks of less than 32 irqs per bank. Looking at all users of generic irq chip, this doesn't appear to be needed. All users are either a single generic irq chip per node or have 32 irqs per bank. Both are supported by this patch series. If bank masking is needed, it can be added later.
This is based on Grant Likely's irq domain work and is available here:
