- * rt5668_sel_asrc_clk_src - select ASRC clock source for a set of filters
- * @component: SoC audio component device.
- * @filter_mask: mask of filters.
- * @clk_src: clock source
- *
- * The ASRC function is for asynchronous MCLK and LRCK. Also, since RT5668 can
- * only support standard 32fs or 64fs i2s format, ASRC should be enabled to
- * support special i2s clock format such as Intel's 100fs(100 * sampling rate).
- * ASRC function will track i2s clock and generate a corresponding system clock
- * for codec. This function provides an API to select the clock source for a
- * set of filters specified by the mask. And the component driver will turn on
- * ASRC for these filters if ASRC is selected as their clock source.
