Hi Alison,
Please always add the driver maintainers (Xiubo Li and Nicolin Chen).

This could be simplified to: static SIMPLE_DEV_PM_OPS(fsl_sai_pm, fsl_sai_suspend, fsl_sai_resume);
I am also curious as to how you tested it, as I noticed that suspend/resume is broken on 3.18-rc for mx6sx.
Are you able to do suspend/resume on 3.18-rc on a mx6sx sdb board?
