I plan to propose an API based on DRM object/properties, which will be
similar to KMS atomic API. I will let you know when I have it ready for
presenting in public.

This patch removes unused entries from exynos_drm_private strcuture.
da_start/da_space_size were only used in drm_create_iommu_mapping()

This patch adds a check if all devices belonging to Exynos DRM have the
same dma_map_ops set. This is required to enable operation with IOMMU
enabled.
