Subject: [PATCH 4/5] ARM: gic: allow irq_start to be 0
Date: Wed, 14 Sep 2011 11:31:39 -0500	[thread overview]
Message-ID: <1316017900-19918-5-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1316017900-19918-1-git-send-email-robherring2@gmail.com>

From: Rob Herring <rob.herring@calxeda.com>

There's really no need to set irq_start per platform for the primary gic.
The SGIs and PPIs are not handled as normal irqs, so how irqs 0-31 are
setup doesn't really matter. So allow irq_start to be set to 0 to match
the linux irq numbering.
