/**
* rt5670_sel_asrc_clk_src - select ASRC clock source for a set of filters
* @codec: SoC audio codec device.
* @filter_mask: mask of filters.
* @clk_src: clock source
*
* The ASRC function is for asynchronous MCLK and LRCK. Also, since RT5670 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 codec driver will turn on ASRC
* for these filters if ASRC is selected as their clock source.
