However, -for Freescale SoCs (especially those released in recent years), most of them -have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And -this is a specific feature that might be painstakingly controlled and merged -into the Simple Card. - -So having this generic sound card allows all Freescale SoC users to benefit -from the simplification of a new card support and the capability of the wide -sample rates support through ASRC. - -Note: The card is initially designed for those sound cards who use AC'97, I2S - and PCM DAI formats.
