Can the iMX8M support the CS42888 in linux

Can the iMX8M support the CS42888 audio codec in yocto linux, or is support only for SOCs with ESAI support at the moment?

 

https://github.com/Freescale/linux-fslc/blob/4.14-2.0.x-imx/Documentation/devicetree/bindings/sound/imx-audio-cs42888.txt

 

The device tree file says to specify "The phandle of the i.MX SSI controller", but the variable is "esai-controller"...

 

The iMX8M-Mini has "one SAI with 4 TX and 4 RX lanes" that seems a good fit, can you just pull down the 2 unused pins? 

 

Thanks,

Nathan
