title: Freescale Generic ASoC Sound Card with ASRC support
description:
The Freescale Generic ASoC Sound Card can be used, ideally,
for all Freescale SoCs connecting with external CODECs.
The idea of this generic sound card is a bit like ASoC Simple Card.
However, for Freescale SoCs (especially those released in recent years),
most of them have ASRC 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. However, it'll be also possible to support those non
AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
long as the driver has been properly upgraded.
