 *
 * 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.
