What did solve the problems? should be 0e764a01015dfebff8a8ffd297d74663772e248a ("iommu/arm-smmu: Allow client devices to select direct mapping") I still need to confirm whether qcom_iommu needs a similar thing, but I think it is ok as the iommu phandle link is down one level on the 'mdp' device, rather than attached to the toplevel drm device.
