However, aic3x specific only. Would it work if there is some set_mclk(int enable) callback in struct aic3x_setup_data, then codec->write in aic3x_init points to higher level aic3x_write_xxx which takes care of calling set_mclk(1) when needed and call aic3x_write? Also delayed set_mclk(0) can be put into aic3x driver. Machine driver can then decide will it provide the callback.
