The below series of patches support the KeemBay ASoC driver. It enabled the tlv320aic3204 machine driver and the platform driver initialize the i2s to capture and playback the pcm data on the ARM. The i2s is running in polling mode.
There is no DSP in the KeemBay SoC. Users are rely on the Gstreamer plugin to perform some Audio preprocessing.
Change History: v2: - Corrected I2S naming for DT binding.
v1: - Initial version.
