Subject: [RFC PATCH 04/12] ARM: versatile: use remapped PPI interrupts for local timer
Date: Wed, 20 Apr 2011 20:08:13 +0100	[thread overview]
Message-ID: <1303326501-15664-5-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.

Tested on VExpress and PB-11MP.
