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. Kind regards Uffe
