Subject: [PATCH 08/13] clk: declare clk_ops of basic clks in clk-provider.h
Date: Wed, 11 Apr 2012 18:02:46 -0700	[thread overview]
Message-ID: <1334192572-12499-9-git-send-email-mturquette@linaro.org> (raw)
In-Reply-To: <1334192572-12499-1-git-send-email-mturquette@linaro.org>

From: Shawn Guo <shawn.guo@linaro.org>

Besides the static initialization, the clk_ops of basic clks could
also be used by particular clk type being subclass of the basic clks.

For example, clk_busy_divider has the same clk_ops as clk_divider,
except it has to wait for a busy bit before return success with
.set_rate.  clk_busy_divider will somehow reuse clk_ops of clk_divider.

Since clk-provider.h is included by clk-private.h, it's safe to move
those clk_ops declaration of basic clks form  clk-private.h into
clk-provider.h, so that implementation of clks like clk_busy_divider
above do not need to include clk-private.h to access those clk_ops.
