Add machine driver for i.MX boards that have AK4458/AK5558/AK4497/AK5552 DAC/ADC attached to SAI interface.
Why? Does simple-audio-card don't fit?
No. We need to support asrc->sai->codec case, but simple-audio-card don't support it. simple-audio-card needs the cpu dai is dummy on BE. And we need to support the DSD format, this driver help to switch the dai fmt from pdm to i2s according to the DSD or non-DSD.
