IMX6Q software to support WM8280/WM8281

Customer is using the IMX6Q and the Cirrus Logic WM8281 audio codec.


I am working on the machine driver portion and the imx6 features, specifically understanding the bare minimum needed to get I2S/SSI, ASRC and the audmux properly configured.


Searching the web I found that NXP has made software for the WM8280 (which the WM8281 is virtually identical and use the same drivers):


I am looking for a reference/starting point for the ASoC “machine code” and device tree which includes a WM8280/WM8281 with ALSA. I believe somebody must have done to interface with this software. Any help is greatly appreciated.
