This series started from the applied and then reverted [2] patch by Robin Murphy [1]. After the MDSS rework [3] has landed it is now possible to reapply the extended version of the original patch. While we are at it, also rework the IOMMU init code for DPU and MDP5 drivers.
For MDP5 this moves iommu_domain_alloc() call and removes struct mdp5_cfg_platform remains.
For DPU this allows specifying the iommus = <...> either in the DPU device (like all DPU devices do) or in the MDSS device (like MDP5 devices do).

Dmitry Baryshkov (3): drm/msm/dpu: check both DPU and MDSS devices for the IOMMU drm/msm/mdp5: move iommu_domain_alloc() call close to its usage drm/msm: Stop using iommu_present()
