Subject: [PATCH v13 0/2] Add memory bandwidth management to NVIDIA Tegra DRM driver

This series adds memory bandwidth management to the NVIDIA Tegra DRM driver,
which is done using interconnect framework. It fixes display corruption that
happens due to insufficient memory bandwidth.

Tegra memory drivers already got the interconnect API support and DRM patches
were a part of the series that added ICC support to the memory drivers, but
the DRM patches were left out unreviewed and unapplied. Hence I'm re-sending
the DRM changes in this new standalone series.

Changelog:

v13: - No code changes. Patches missed v5.12, re-sending them for v5.13.

Dmitry Osipenko (2):
  drm/tegra: dc: Support memory bandwidth management
  drm/tegra: dc: Extend debug stats with total number of events
