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 (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 driver. So having this driver will allow all Freescale SoC users to benefit from the simplification to support a new card and the capability of wide sample rates support through ASRC. The driver is initially designed for sound card using I2S or PCM DAI formats. However, it's also possible to merge those non-I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, into this card as long as the merge will not break the original function and as long as there is something redundant that can be abstracted along with I2S type sound cards. As an initial version, it only supports three cards that I can test: imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver imx-audio-wm8962, just like the old imx-wm8962.c driver The driver is also compatible with the old Device Tree bindings of WM8962 and SGTL5000. So we may consider to remove those two drivers after this driver is totally enabled.

initial machine driver for the ES8328 audio codec on Freescale boards. The driver supports headphones and an audio regulator for an onboard speaker amp.

That string is also used in the omap3-n900.dts file. However, the connector driver uses "composite-video-connector", so this has never worked. While changing the driver's compatible string to "composite-connector" would be safer, as published DT bindings should not be changed, I'd rather fix the bindings in this case for two reasons: * composite-connector is a bit too generic name, as it doesn't even hint at video. * it's clear that this has never worked, which means no one has used those bindings, which should make it safe to change this.
