Subject: [RFC PATCH v4 05/13] ARM: versatile: use remapped PPI interrupts for local timer
Date: Fri, 27 May 2011 17:27:43 +0100 [thread overview]
Message-ID: <1306513671-12206-6-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.
Tested on VExpress and PB-11MP.
Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
