From 4c18e77f718cdda33363132127db4df795eadbd9 Mon Sep 17 00:00:00 2001 From: viresh kumar Date: Mon, 3 May 2010 09:24:30 +0100 Subject: ARM: 6091/1: ST SPEAr: Adding support for shared irq layer Multiple peripherals in SPEAr share common hardware interrupt lines. This patch adds support for a shared irq layer, which registers hardware irqs by itself and exposes virtual irq numbers to peripherals.
