Does this example from mxs-saif help?
commit 7c9e6150f2e7cbd60e0bc9a19118ca1dc97d2780 Author: Shawn Guo <shawn.guo@linaro.org> Date: Mon Jul 1 16:16:10 2013 +0800
ASoC: mxs: register saif mclk to clock framework
Mostly the mxs system design uses saif0 mclk output as the clock source of codec. Since the mclk is implemented as a general divider with the saif clk as the parent clock, let's register the mclk as a basic clk-divider to common clock framework. Then with it being a clock provdier, clk_get() call in codec driver probe function will just work.
