Subject: [DT] API to determine if interrupt is PPI or SPI ?
Date: Thu, 26 Jul 2012 12:18:41 -0700 (PDT)	[thread overview]
Message-ID: <53a41d02c4c4c24bdab47667183891bf.squirrel@www.codeaurora.org> (raw)

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 ?

Thanks,
Rohit
