Subject: [PATCH 14/22] msm: clock: Support clk_set_parent() clk_ops
Date: Thu, 16 Dec 2010 16:49:58 -0800 [thread overview]
Message-ID: <1292547006-19741-15-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1292547006-19741-1-git-send-email-sboyd@codeaurora.org>
Voting clocks are linked to the clock they vote on with a parent
pointer. Implement this API for sub drivers which wish to use it.
