7 title: Freescale Generic ASoC Sound Card with ASRC support
10   The Freescale Generic ASoC Sound Card can be used, ideally,
13   The idea of this generic sound card is a bit like ASoC Simple Card.
16   be painstakingly controlled and merged into the Simple Card.
18   So having this generic sound card allows all Freescale SoC users to
19   benefit from the simplification of a new card support and the capability
22   Note, The card is initially designed for those sound cards who use AC'97, I2S
24   AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
