Subject: [PATCH 8/8] OMAP2+: clockevent: late-init GPTIMER clockevent hwmod right before timer init
Date: Wed, 23 Feb 2011 00:11:54 -0700	[thread overview]
Message-ID: <20110223071153.5874.58923.stgit@twilight.localdomain> (raw)
In-Reply-To: <20110223070455.5874.51326.stgit@twilight.localdomain>

Late-initialize the GPTIMER hwmod used for the clockevent source immediately
before it is used.  This avoids the need to late-initialize all of the hwmods
until the boot process is further along.  (In general, we want to defer
as much as possible until late in the boot process.)
