Subject: [PATCH 06/14] omap: Fix dmtimer.c for multi-omap boot
Date: Tue, 26 Jan 2010 12:12:48 -0800	[thread overview]
Message-ID: <20100126201248.15382.66154.stgit@baageli.muru.com> (raw)
In-Reply-To: <20100126200646.15382.52167.stgit@baageli.muru.com>

Fix dmtimer.c for multi-omap boot. Also remove legacy
clk_enable/disable wrappers that are no longer needed.

Note that the clock handling should be further improved
to make use of the clock aliases.
