Subject: [PATCH 2/4] clk: Implement clk_set_rate
Date: Fri, 20 May 2011 07:27:49 +0000	[thread overview]
Message-ID: <1305876469.326620.351525457111.2.gpush@pororo> (raw)
In-Reply-To: <1305876469.325655.313573683829.0.gpush@pororo>

Implemenent clk_set_rate by adding a set_rate callback to clk_hw_ops,
and core code to handle propagation of rate changes up and down the
clock tree.
