Subject: [PATCH 7/8] OMAP4: clock: Add CPU local timer clock node.
Date: Thu, 8 Sep 2011 10:52:06 +0530	[thread overview]
Message-ID: <1315459327-3285-8-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1315459327-3285-1-git-send-email-santosh.shilimkar@ti.com>

Local timer clock is sourced from the CPU clock and hence changes
along with CPU clock. These per CPU local timers are used as
clock-events, so they need to be reconfigured on CPU frequency
change as part of CPUfreq governor.

Newly introduced clockevents_reconfigure() needs to know the
twd clock-rate. Provide a clock-node to make clk_get_rate() work
for TWD.
