Subject: [PATCHv3 4/4] arm: Add generic timer broadcast support
Date: Mon, 14 Jan 2013 17:05:24 +0000	[thread overview]
Message-ID: <1358183124-28461-5-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1358183124-28461-1-git-send-email-mark.rutland@arm.com>

Implement timer_broadcast for the arm architecture, allowing for the use
of clock_event_device_drivers decoupled from the timer tick broadcast
mechanism.
