Subject: [PATCH v2 8/8] ARM: OMAP2+: timer: use a proper interface to get hwmod data
Date: Mon, 27 Feb 2012 22:37:10 -0700	[thread overview]
Message-ID: <20120228053707.16278.35928.stgit@dusk> (raw)
In-Reply-To: <20120228053524.16278.59430.stgit@dusk>

arch/arm/mach-omap2/timer.c pokes around inside the hwmod data
structures.  Since the hwmod data structures are about to change, this
code will break.  This patch modifies the timer code to use
recently-added hwmod functions instead.
