That's not a valid assumption as far as I remember? The AIFs can use either MCLK depending on the system configuration I think. > If clock rate is let 0, the frequency provided by > wm8994_set_dai_sysclk() is used instead. I'd expect this the other way around, if we didn't specify a frequency then read it from the input otherwise try to use clk_set_rate() to propagate things up.
