[alsa-devel] iMX6 SSI driver: fsl_ssi vs imx-ssi

Hi community,

I am developing an ASOC codec driver based on iMX6SL platform. I noticed there are fsl_ssi.c and imx-ssi.c in folder sound/soc/fsl.

Would you please tell me what are the differences between these 2, and which one should I use? Thanks.
