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.
