[Freedreno] [PATCH 0/3] drm/msm: fixes for KMS iommu handling

[Dmitry Baryshkov]

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()
