[PATCH 0/3] drm/tegra: A couple of fixes for v5.6-rc1

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

Hi,

this contains a couple of fixes for a DMA API performance regression
that was introduced in v5.5 for older Tegra devices. Patches 1 and 2
will likely have to be backported to v5.5.

  drm/tegra: Relax IOMMU usage criteria on old Tegra
  drm/tegra: Reuse IOVA mapping where possible
  gpu: host1x: Set DMA direction only for DMA-mapped buffer objects
