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.
Changelog:
v14: - Made improvements that were suggested by Michał Mirosław to v13:
- Changed 'unsigned int' to 'bool'.
- Renamed functions which calculate bandwidth state.
- Reworked comment in the code that explains why downscaled plane
require higher bandwidth.
- Added round-up to bandwidth calculation.
- Added sanity checks of the plane index and fixed out-of-bounds
access which happened on T124 due to the cursor plane index.
v13: - No code changes. Patches missed v5.12, re-sending them for v5.13.
