Is it possible to control I2S/SAI controller from A7 domain in iMX7ULP?


By default, I2S/SAI drivers are available in M4 SDK (part of FreeRTOS) provided in the release package and are enabled by default to work with wm8960 codec. I could also see drivers available in linux (sound/soc/fsl/fsl_sai.c) and it is compatible with imx7ulp. So, can we control the I2S/SAI from A7 (Linux) itself ?
