| 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. |
