Subject: [PATCH 07/26] ARM: OMAP: dmtimer: Have __omap_dm_timer_load_start set ST bit in CTRL instead of caller
Date: Thu, 24 Apr 2014 16:43:50 -0500	[thread overview]
Message-ID: <1398375849-6017-8-git-send-email-joelf@ti.com> (raw)
In-Reply-To: <1398375849-6017-1-git-send-email-joelf@ti.com>

"load_start" implies start, so it makes sense to set the ST bit in
__omap_dm_timer_load_start instead of callers.
