Quick question above "imx_soc_platform" and DT's "sai3" are implemented at same driver ? If so, I guess your kernel doesn't have this commit ? If not, please include it. 9f3eb917534511f2e275b7cf63ed76374ade77bc ("ASoC: simple-card-utils: consider CPU-Platform possibility") Sorry to bother you. Thank you for your help !!
