The SDHC controller in the imx8mn and imx8mp have the same controller
as the imx8mm which is slightly different than that of the imx7d.
Using the fallback of the imx8mm enables the controllers to support
HS400-ES which is not available on the imx7d. After discussion with NXP,
it turns out that the imx8qm should fall back to the imx8qxp, because
those have some additional flags not present in the imx8mm.

I didn't quite follow all the discussions on patch3 - and whether that
may affect the binding. Anyway, I assume you will send a new version.
If not, please tell and will pick this up.

 I am not sure exactly how the YAML should look, but I'm going to give
it a try.  I hope to have something this weekend.
