Okay, I will check if I miss to correct some previous comments.

Other compatibles are surely needed to be in our driver, I will correct it in our new version, thanks.

Sorry for asking. Which dts do we need to link it? The device tree we use for our SOC?

or realtek,rtd-dw-cqe-emmc.example.dts?  Thanks.

This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully addressed. Maybe the feedback got lost between the quotes, maybe you just forgot to apply it. Please go back to the previous discussion and either implement all requested changes or keep discussing them.

Thank you.

Additionally:

A nit, subject: drop second/last, redundant "bindings for". The "dt-bindings" prefix is already stating that these are bindings.

I asked which ones. I still do not see that information here.

That's not what is present in your driver. Why other compatibles are not there? What do you want to express here?

Use proper interrupt defines instead of raw values.

Where is the DTS implementing this binding?

I said it once:

I still do not see DTS anywhere. Please link it.
