Subject: [RFC PATCH 06/12] ARM: ux500: use remapped PPI interrupts for local timer
Date: Wed, 20 Apr 2011 20:08:15 +0100	[thread overview]
Message-ID: <1303326501-15664-7-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1303326501-15664-1-git-send-email-marc.zyngier@arm.com>

Use the normal interrupt scheme for the local timers by using
a remapped PPI interrupt.
