Subject: [PATCH 07/11] ARM: sa1100: convert timer suspend/resume to clock_event_device
Date: Thu, 8 Nov 2012 14:01:52 -0700 [thread overview]
Message-ID: <1352408516-21988-9-git-send-email-swarren@wwwdotorg.org> (raw)
In-Reply-To: <1352408516-21988-1-git-send-email-swarren@wwwdotorg.org>
From: Stephen Warren <swarren@nvidia.com>
Move sa1100's timer suspend/resume functions from struct sys_timer
sa1100_timer into struct clock_event_device ckevt_sa1100_osmr0. This
will allow the sys_timer suspend/resume fields to be removed, and
eventually lead to a complete removal of struct sys_timer.
