Hello,

We can specify the interrupt information in the device tree using the arm
gic convention.
Is there an API to read directly the 1st cell and determine if an
interrupt is a PPI or a SPI ? This information is directly relevant to the
driver because it needs to call request_irq or request_percpu_irq based on
this data.

How should this be done ideally ?

Seems a bit strange to me that you would have a h/w block that can be
connected either way...

Perhaps the irq resource should have a flag for percpu irq.
