^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 1) Freescale Generic ASoC Sound Card with ASRC support
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) SoCs connecting with external CODECs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) The idea of this generic sound card is a bit like ASoC Simple Card. However,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) for Freescale SoCs (especially those released in recent years), most of them
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) this is a specific feature that might be painstakingly controlled and merged
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) into the Simple Card.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) So having this generic sound card allows all Freescale SoC users to benefit
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) from the simplification of a new card support and the capability of the wide
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) sample rates support through ASRC.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Note: The card is initially designed for those sound cards who use AC'97, I2S
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) and PCM DAI formats. However, it'll be also possible to support those non
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) long as the driver has been properly upgraded.
