See omap4_func_mcbsp2_gfclk_parents[] and omap4_mcbsp2_bit_data[]. I'd just use assigned-clock-parents on the internal clock, and possibly also for the clksel clock in the board specific dts file. This way the mcbsp driver doing pm_runtime_enable() will enable the clkctrl modulemode and the rest of the clock configuration should happen automatically. Regards, Tony
