Subject: [RFC PATCH v4 06/13] ARM: shmobile: use remapped PPI interrupts for local timer
Date: Fri, 27 May 2011 17:27:44 +0100	[thread overview]
Message-ID: <1306513671-12206-7-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1306513671-12206-1-git-send-email-marc.zyngier@arm.com>

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