Does this example from mxs-saif help?

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.
