[PATCH v1 0/3] Tegra DRM: Support memory bandwidth management for display

[Dmitry Osipenko <digetx@gmail.com>]

Hello,

Display controllers have a need for minimum memory bandwidth in order to
maintain data-stream to output at a required rate. There is a visual
corruption once the requirement is violated and CRTC reset may be required
in order to recover. This series adds preliminary support for the memory
bandwidth management, it will become active once Memory Controller drivers
will get support for the PM memory bandwidth QoS.

  drm/tegra: dc: Tune up high priority request controls on Tegra20
  drm/tegra: dc: Extend debug stats with total number of events
  drm/tegra: Support PM QoS memory bandwidth management
