Hi Dave,
The following changes since commit 9a42c7c647a9ad0f7ebb147a52eda3dcb7c84292:
drm/tegra: Move drm_dp_link helpers to Tegra DRM (2019-10-23 18:22:10 +0200)
are available in the Git repository at:
git://anongit.freedesktop.org/tegra/linux tags/drm/tegra/for-5.5-rc1
for you to fetch changes up to 84db889e6d827eefc3dde130fec8382d2dcb23ac:
drm/tegra: Unconditionally select IOMMU_IOVA (2019-11-01 10:49:29 +0100)
Note that this is based on the drm-misc-next-2019-10-24-2 tag which
contains the DP link helper move into the Tegra DRM driver. The diffstat
below shows only the differences since that tag, since the other changes
have already been merged as part of drm-misc-next.

drm/tegra: Changes for v5.5-rc1
The bulk of these changes is the addition of DisplayPort support for
Tegra210, Tegra186 and Tegra194. I've been running versions of this for
about three years now, so I'd consider these changes to be pretty
mature. These changes also unify the existing eDP support with the DP
support since the programming is very similar, except for a few steps
that can be easily parameterized.
The rest are a couple of fixes all over the place for minor issues, as
well as some work to support the IOMMU-backed DMA API, which in the end
turned out to also clean up a number of cases where the DMA API was not
being used correctly.
