Please add a node including sdhc3 lpcg iomem, and mark passthrough, no need smmu entry for it. Check how lpuart passthrough in imx8qm-mek-dom0.dts.

Hello,

Unfortunately, the i.MX8QM is still in preproduction and we do not have any preliminary documentation about the product. I recommend you to go with your DFAE. He could help you with this problem.

I apologize for the inconveniences this could give you.

Best regards,

Diego.
