Subject: [PATCH v4 7/7] ARM: architected timers: remove support for non DT platforms
Date: Fri, 27 Apr 2012 13:55:59 +0100	[thread overview]
Message-ID: <1335531359-32128-8-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1335531359-32128-1-git-send-email-marc.zyngier@arm.com>

All mainline platforms using the ARM architected timers are DT
only. As such, remove the ad-hoc support that is not longer needed
anymore.
