This needs a binding document update too.

What's the difference between imx6sx-sai and imx7d-sai?
I think you may put its compatible model in the DT instead of adding a copy in the driver unless the SAI on the imx7d really has something different.
For example: compatible = "fsl,imx6q-ssi", "fsl,imx51-ssi"; /* The driver only has imx51-ssi */

The imx7d-sai is the same as imx6sx-sai, so i should use compatible model "fsl,imx6sx-sai" for imx7d-sai.

It's generally good to have compatibles in the DT even if we believe the hardware is identical since it can happen that differences are found later (either due to new features being added or bugs found) and having the explicit compatibles in DT already means that we only need to update the driver.
i.MX6ul SoC contains SAI module, so add imx6ul platform support.

I notice that you're adding support for new platforms along with this - does this support depend on the platform? You should also have a note in the commit log explaining that there are no code changes required in the driver except the capability define since it already just writes the width directly to the hardware.
